I am dyslexic and fell through the system. Im in my 40s and am still shaky with math. I’m so upset that things like this weren’t taught. I couldn’t even ask “can you explain it a different way?” back then because I didn’t know to do that. Thank you so much for this easy explanation. I’m going to keep practicing.
A really nice simplification method! So cool I almost feel like I’m one of the "smart kids". (I’m almost 72. But smarter than yesterday!) Thanks for your amazing videos!
I'm crying. I know this feels like an overreaction, but I had SO MUCH TROUBLE understanding this when I was in school, and I was definitely taught the first method which took me ages. Math kind of terrifies me lol, so I don't know why CZcams recommended me this, but I'm glad I clicked. Thank you so much, sir, God bless you.
I mean, math in school also teaches you logic. There's no point in just memorizing shortcuts without understanding what you're doing.
This shortcut is OK if you actually know what you're doing and why you're doing it.
@@ezicarus8216 The Imperial system is fine and the metric system has its own problems. It's not strictly "better" in any case. The American public education system is a joke, but not everyone in America uses it - private and home schools exist, and both achieve superior results. Not to mention some other nations have their own problems with their education system.
Be a little less anti-America and you can actually appraise and analyze things rationally.
@@SubduedRadical👏🏾👏🏾👏🏾 Here's a π 🥧
Growing up in the 60's I was taught the longest way possible to get the answers and we had to show our work!!! The only thing this achieved was over complicating it and turning me against math. I now have a son who teaches math at the university in the city we live in.
Liked & subscribed!
80s I was taught like this.
That’s kind of cool. Instead of learning math you just raised a son who is a math professor. Lol. 👍🏼
@@Iansco1 When you say "like this", are you meaning like this video or the long / old way like DC BC was pointing out?
I'm curious because you comment could be taken either way and as someone who also grew up leaning fractions in the early 80's, it was the long / old way for me. This then makes me wonder just how much things varied across the country / around the world back then if your comment was meaning the way of the video rather than the old way as mentioned in the original comment yours was in reply to.

Wait there are people that just don't go 3+2 + 1/3+1/4?
Next you'll tell me there are people that count on their fingers to add numbers.
I thought my math teacher was genius. His approach was to teach every possible way to achieve a correct answer, because some methods were easier for different people to use. Then he would also give the quickest method and shortcuts. To me, it made a boring subject very interesting.
I would of loved math with a teacher like that instead of the assholes I had.
@@patsmith378 Your English teacher didn't do a very good job either.
My friend and I would always fight when adding up linear feet for building projects I'd say his method was wrong , he said the same for me HOWEVER we always got the same answer as each other just different approaches to get there!!
Sounds like a great teacher.
@@Chilliam13 You would shine in Nazi germany!
I actually caught on for the first time since math class 30 years ago! No one ever cared if you caught on, if you were shy like I was and afraid to ask for help, you just got left behind. Then the teacher would make several kids come up to the chalkboard and give you a problem to solve and I would go blank. I’d still be standing there like an idiot in front of all the other kids who were snickering and laughing at me. This gave me massive anxiety and made me feel like I was totally stupid. I wish I would’ve had someone like you to break it down on such a basic level. I’m 50 now and finally know how to do the problems! Thank you so much!
This is exactly how I learned to do fractions in the 80s. Last year my nephew stayed for a few days and somehow someone came up with a very complex formula to do fraction with is called common core math. My nephew tried to explain it to me, but I still don't fully understand it...
Omg, my sister-in-law is being taught “common core math.” It’s the most confusing, drawn out thing I’ve ever seen. Simplicity is key.
Its dumb.
I'm so glad I learned the fundamentals before they went to Common Core. I got this easily because this is just elementary algebra. I struggled with math as it is with the regular curriculum. With CC, I'd be screwed!

I’m 42 and I absolutely love your channel. I went to a special school when I was younger so I never was able to fully reach my potential in maths, as teaching resources where allocated to the more disabled students. Viewing your channel as made me fall in love with maths and I’m currently helping my niece with the great aid of your channel.
Thanks for that kind comment.
Hope you are learning a lot!
Thank you for your refresher course. I wish there were more “simple math” taught in schools. It saves time and teaches our youngsters the easiest ways to solve mathematical equations.
I was taught the "proper" way back in school (turn to improper fraction then add), but learned this by myself and it saved a whole lot of time. The trick with math is to analyze and find patterns that help you solve faster. Don't just copy how your teacher did it. Understand how the equations work and find better ways to solve your problems.
The problem arrives when teachers don't give you full points because you didn't solved it "their" way.
@@xXEliminatorXx99 true. I had teachers/professors like that. You just have to adjust in those situations. Like, for myself, I still study how my teachers did it and I just used their methods if required.
Improper fractions add extra steps and get complicated when you have bigger numbers. There are easier ways to do mixed numbers than putting them into improper fractions.
This is the process I was taught in the 60's, and ended up majoring in math. The hoops they put students through now are simply distractions. Straightforward and to the point -- that's how math works.
Yep, exactly what I was taught in the 60's as well.
@@paulg4767 But were you taught why it works?
Math is racismzsz!! REEEEE!!
@@sclogse1 I was taught this way in the 60s too. And yes it was explained, it's not like it has a difficult theoretical basis.
And how I was taught in the 80's.
What a great way to approach these operations. K-12 schools in the US teach math in the most tedious, nonsensical way; that’s why I never enjoyed it as a kid (it’s probably the same way in AU). Now as someone studying math as an adult back in school, it’s so much more interesting and enjoyable thanks to channels like this one. Thanks!
Teachers teach teachers, who in turn teach teachers!
Bad explanations, inefficient techniques are passed on down the line, through the generations.
@@tecmath What drives ME MAD is when I taught my kids shortcuts they got the right answer but because they showed THIS WORK and not what the teacher taught they go ZERO CREDIT for the problem.
I grew up in the early 80s in California and was taught this method. Are they teaching kids it differently now? I thought they were teaching more efficiently since they have time to teach CRT and gender studies to elementary kids.
@@vickiliao7171 yes they teach common core math nowadays which is so ridiculously tedious!
This is how I was taught in the nineties. How else do you do it?
I taught fractions for 35 years. This isn’t a “trick”…..it’s good teaching.
Thank you for your service Ma'am
Exactly how I was taught back in the early 80s
Imagine thinking good teaching isn't all tricks. Math is as much invented as discovered (some debate on that topic), it's all just trying to make a reliably computational system to combine numbers in various ways
That's great, but a lot of teachers think it's best to add to the fractions and then combine rather than doing everything in one step. The fixation on showing work creates difficulties in students.
Exactly
I was taught the long way in the 50's and had great difficulty understanding fractions, period. With your explanation I can finally see the answer within a minute.
Mind boggling how I was taught was no where near as simple.

Same here, a science lover...minus math. This helps, but too bad math progresses very quickly from there...enter calculus (with no tech.calculator)...and much more...I am still hopeful, and still teachable though.
I failed math in high school. Not because I couldn't understand it but because I had a tendency to skip classes. While I could laboriously figure out some problems, without knowing the standard methodologies used in algebra, geometry and so on, I came to believe most math was beyond me. Many years later I'm fascinated by mathematics. While it's far too late for me to atone for my poor performance in school, I'm now enthralled by everything mathematics. Love this channel.
Huh. You just managed to teach me in under a minute, something that I've hated and feared my entire life, because math and I just don't get along. This was so cool, thank you!
I was taught the "hard and long" textbook way in the '60s. Teachers who didn't know their math enough to show us how to easily solve it and move on to the next level, consequently a lot of us got stuck and never saw the beauty of math. Relearning it the "better" way now.
In my small town were also taught the hard and long method in the 80's by teachers in their 80's.
@@BeingBoringx2 lol...
Same here.
I have a vivid recollection of that happening in the '70's, my incompetent teacher got frustrated with me and just moved on. Many years later I learnt to do fractions with a mixture of mental gymnastics and logic, and went on to become a civil engineer. I've often wondered how much easier my studies would have been if those early teachers didn't suck.
@@fredflintstone8770 Yep. I never got fractions and so never got through Algebra. I hack fractions by converting to nearest decimal eg 3/4 = .75 and got by that way. So much good instruction available today we never got :). Best Regards
This guy takes the fear out of maths and most of us know, how hopeless we at even the simplest dums so this is a godsend.
Thanks mate. I really try to make it not scary - and also try to find the confusion point!
This was taught with students in the 60's till the 70's I remember from elementary and high school doing this (as I often been asked to be a sub teacher whenever my math teacher was in a meeting. We are deeply blessed to have a genius professors and teachers in those eras.
I was taught this in the 90s and early 2000s

Thank you for a refresher course. You simplify it. Which is what makes it exciting for the people who have a hard time understanding. Thank you ☺️
I taught math. Always started with the “book version” as you described as the long way, partly because that was how the text did it and you always have at least one student who needs to learn it that way to understand the trick. Most texts don’t go beyond the long way…but that’s why there is a teacher and not just a book. Students generally get a larger spark of fascination in the magic if you display the tough way first.
Only if the math teacher knows math. Plenty don't. They pounded the book at us and hid the magic behind rote.
@@bgrigg07 I can so relate. Math was such a struggle for me and I did so poorly at it. Now at age 61 I am watching this thinking "damn"!
I'm not a teacher but I taught my little cousin how to do math like this she went from average to first one done with an A. Her little brother, I just couldn't get it took take hold, I tried multiple angles and he would seem like he's understanding, then he fortnited and its gone 😂.
So I understand teaching the book first, you have to know how things work before you can really start doing tricks/hacks.
If you can read this, thank a teacher!
Never seen this before and I Love math
I love that logic, loads better than how I initially learned it.
How did you learn it?
@@hotjanuary I asume the wright way cause in this video it's false. First calculation is 2.(1/3)+3.(1/4), the result should be 17/12 and not 5.(7/12)=35/12, use a calculator if you need a better proof than me
@@williamrio8184 the answer is 4 17/12...reduced to 5 5/12
I'm 69 and I remember my math teacher in grade school drilling us with the method you first mentioned. Most of my math teachers stressed memorization and procedures, very boring to me, whereas I was always trying to do math intuitively. In high school I tuned out the math classes and studied math on my own, including Calculus. I later made up for the deficiencies I had from my self-taught regimen and eventually wound up getting BS & MS degrees in Physics with a strong background in applied math.
Nice
Nice
Being in my 40's, seeing this now brings back all the stress and anxiety from grade school. Where were you then?!? This is a beauty. Thanks!
I've always done a mixed approach. When adding fractions, I always just add the whole numbers and convert the fractions in my head if they have simple conversions. However, when subtracting mixed numbers, I prefer to turn them into improper fractions because I may have to borrow from the whole number in order to get it to work, so that takes out any errors for me.
This is how I was taught in the 60s.
The problem I have with teachers showing kids the more difficult/time consuming way to do math problems when they’re in elementary school is that it confuses young kids. My daughter was struggling with math in 5th grade, and when I asked her teacher about it at conferences, she blasted me for not being supportive about her other grades, which were very good. SO helpful. In the sixth grade, she was flunking math and was so embarrassed that she quit turning in her homework. The teacher called us and I picked up the homework for that night. I sat her down and when we got to division problems, she had no idea how to do them. I showed her the way my fifth grade teacher (in 1970) showed us. She said they didn’t learn anything like that. She picked it up like nothing, and continued to gets As in math until she graduated high school. It was her favorite subject.
Simple tricks in mathematics are great when you have the understanding of what you really do. If you don’t understand it, it’s worthless! As a teacher in mathematics I always work with my pupils understanding first😊
I do not understand this whole idea of "simple tricks" to arrive at the correct answer to a mathematical problem. You write down all of the steps taken to arrive at the correct answer to the question. Even if you arrive at the correct answer, but make a mistake in the calculations that lead you to the answer, you are still wrong!
@@jonathanshreiner9
That’s why you have to be sure of your calculations. It’s self explanatory. At least, it is to me…
I totally agree Gunnar. I taught maths for 10 years and most pupils need to be told things step by step because they don’t understand the underlying principles.
5 7/12
Narrator's voice is so cool, feels like keep on listening to him. Thank you for your presentation and awesome math solutions.
I was never taught that trick, but I figured it out on my own. I never understood why we needed to make a giant fraction from the whole numbers first, when adding them up straight away was easier. Plus fewer multiplies and divides. And adding the whole parts gives you a lower bound on the answer and a sanity check on the final answer.
Another fun exercise! It has been over six decades since I last did mixed fractions. I am surprised that I remembered how to do these. 🤗💚
Great work!
The reason you're surprised is because I would dare say, like me, I've never encountered an instance in the "real world" where I've need to use this skill, in the 60 years since I learned it in high school.
@@dhyde9207 I do it in baking all the time. I’m always changing recipes to be larger or smaller or splitting a recipe into 1/3 and 2/3 as I just did recently. When using one whole recipe to make two different batches of bread (one GF, on regular) that was division but 🤷🏼♀️ same thing pretty much. Honestly it was mostly just educated guesswork. Lol but I did some math
I love how new ways are always being discovered. Thanks for the tip!

Isn’t this what they teach?
Bad idea, this is not a good way to do it. It works well for 1 digit numbers but if you understand lowest common denominator you can do stuff with way more digits way easier than this method would. Math is about understanding why something works and not applying pattern solutions. Pattern solutions are for people in university when university math starts going way over their head - not grade school.

This is great. Thanks for showing me this. I was doing it the long way but using your way I did these in my head easily
I was actually just pleased that I remembered how to at least do it the long way. 😄
But it makes perfect sense; It's not like an obscure trick.
I also tried it with adding more than 2, and it's even more efficient relatively,
because you're not creating huge numbers just to eventually have to break it down again.
Much better!

Then again my math teachers got mad at me when i looked at this problem and refused to show my work for problems i thought were obvious.
what do you remember, LOL
i am 73. that's how i was taught it in 1955.
common denominator. you never learned that?
To be honest this is exactly how I did the work. But, you over simplified the explanation on getting the common denominator. The correct answer is not always going to be multiplying the two denominators together. By using that method of just multiplying them it can sometimes cause more work than you need. I would recommend to people that they find the common denominator in a more traditional way.
How is that faster? I did all this quickly in my head with this method. I would not have been able to quickly do the last example or the one before in my head with a traditional method
That is another lesson
When you are looking at relatively small numbers the method in the video is highly effective. The problem comes when you're talkin about larger denominators. If you just do the multiplication and then later on reduce them, it can sometimes take quite a while. If you take a minute to find the true lowest-common-denominator it can save you trouble later on. Furthermore if you have a huge denominator that means your numerators are going to be huge loss of multiplication lots of opportunities to mess up your arithmetic.
@@realistic-location9213 of course if you start getting to huge denominators then trying to do the math in your head isn't likely to work in the first place which this method is best used for.
@@Lorkanthal very true. But I have found that people tend to make a lot of simple arithmetic errors even in situations with smaller numbers. Sometimes especially because of the small numbers. I spent several years as a math tutor covering this specific subject. It's always been my opinion to try and keep the numbers as simple as possible so as to lessen the chances of simple mistakes

If this had been explained to me in school like this I wouldn’t hate math like I do right now.
Dude, adding mixed number fractions might be the smallest part in all math. I can't believe that someone got overwhelmed from the difficulty just from mixed fractions, since you never find them again and there's not many cases you find them in real life anyway.
I can understand the continuing difficulty of this and other aspects of maths and contributing as a whole to your suffering, but saying you gave up just cause you couldn't calculate easy mixed fractions (which also has another way of getting calculated) is pure BS to me.
I know how you feel.
@@jimmysaboter3 you’re underestimating how complex some teachers made it for no reason. If they taught math this way not so many ppl would of failed math so often.
@@mindyours752 As far as i know there were 2 ways to calculate mixed number fractions.
The first one is the classic one. You transform a mixed fraction to having 2 different numbers. For example 3(1/3) is 3+1/3. Then you make every fraction have a common denominator and you add them all up. This is something you already need to know if before you learn how to handle Mixed Number Fractions.
This way shown in this video is pretty good for 2 mixed fractions but what do you do when you have 3 or more mixed number fractions?
You give up?
You can add the first two of course and then the outcome will be added to the third etc. but it takes time.
To say that this way here is "infinitely easier" than what we've learned at school is bullshit to me. Maybe faster yes, but not easier. Cause you have to remember extra steps.
There's a reason that people are learning the common way to these calculations.
And it is that you can handle whatever they give you without needing a shamanic method like this one. Again, it's fast but you need to remember extra stuff.
Maybe though you can tell me one "Complex way" that teachers have chosen to show kids. Cause no way i've been taught was "complicated".
@@jimmysaboter3 You're underestimating how bad our public school teachers were. The fact you can go through the comments and see everyone flipping out about this solution should let you know this way wasn't taught at all.
that's pretty much what I was taught in the 80s. It's always important to make sure you teach the concept and that students fully understand that, before you go to any 'tricks'.
If the concept is taught correctly, most students will get to this 'trick' by themselves. Although I don't really consider this a trick.
It’s not a trick. It’s just another way of cross multiplying.
I completely think of this as a trick, specifically because it doesn't require any actual comprehension of the skill of combining fractions through evaluating the LCD. Math teachers like me hate trick math because any math teacher worth his/her certificate would know that it sets kids up for failure in high school when they CAN'T use this trick for high school math and beyond. Even in colleges of education in universities, the professors will highly discourage the use of these tricks because of the long term negative implications. This trick becomes completely useless after about 6th grade. Math is all about logical and critical thinking. If you bypass teaching that, you might as well not even bother learning math at all.

We teach fractions in the wrong order. Multiplying is easiest, and you need to know it before adding and subtracting.

I excelled in Maths at school, but it's been a while (lol) - plus this is SO MUCH EASIER! My son would have been lost without your channel - thank you so much x
Thank you
This is how I was taught in elementary school in the 80s. I just assumed this is how everyone does it. I'm now curious how others were taught.
Yeah.. This is how I was taught as well.
Anything else feels overly complicated.
Maybe we learned how so we could also see how it all works from another angle, good to see the sausage being made and all.
But in actual practice, this is what we were taught.
I was in school grade school for the latter half of the 80s. Wonder when this stopped.
Same, in the 80s.
Just showed this to my 13yo.
They taught him this method as well.
They are currently going through a segment where they learn all the division tricks. They learn long division, but then learn the tricks if dividing by 2, 5, 10, and more complex 6, 8, etc.
I'm actually surprised and glad that this teacher is doing this.
Though I shouldn't be surprised.
He's my son's first male teacher, and immediately stopped the years long verbal bullying (that no one could apparently deal with), is into anime (and even gave them some Ghibli movie choices for movie night.. Kids ended up picking Spirited Away), and knows about and supports my kid's love of EDM & DOOM music and FLStudio music making, etc.
I was impressed.
Oh and they played D&D last year for end of school goof off times.
@@kaisokusekkendou1498 To few male teachers. Damned school systems are poisonous for men and boys.
I was learning fractions in the late 90s to early 2000s, we were taught to show every step of our thought process. And by thought process, it means using the formula to find an answer in the teachers edition margins
Thank you. Been struggling with mixed numbers for 60 years.
This is so helpful and saves so much time, thank you!
Omg, this is how I was taught many eons ago, so simple. Excellent maths teacher, he had the patience of a saint. I can see him but cannot remember his name, probably no longer with us, but I can still picture him. 💜
This is exactly how I was taught in elementary school in the 50’s! What happened?
Maybe deppends on the teachers, which country, the time...
Either way... you were not stooged!
same for me in the 70's. Maryland.
Me too, 1970’s U.K. comprehensive. I can’t imagine what other way there could be!
That's exactly how I was taught it... late 1990s/early 2000s Bavaria (Germany)
Same for me in the 80's in the you know dumb south.
Oh god.. i never seen before such wonderful teacher skill.
OMG! You made this SOOOO easy!! Thank you so much!
That's what I teach my students 👏👏
Lovely.
Are classes remote at the moment for you?
I’m glad you’re watching this channel and passing it on. Thanks for being a teacher, I couldn’t do it under contemporary conditions.
This is the way I learned it (Millenial education). I’d like someone to link me an example of the confusing method everyone else is talking about.
That method isn’t confusing. It’s just longer. Turn the mix numbers into improper fractions. Then do what you would normally do when adding fractions. You know…just find the common definition. Then add the fractions and then turn the answer back into a mixed number.
To be fair, you should still know how to convert fractions from improper to mixed, and mixed to improper anyway. They don't teach you how to do this kind of stuff where you've never done any of the steps before. Converting can save the trouble of forgetting to add the extra whole number, like in the third problem of the set of three he shows. By converting first, you're already adding in that extra number. With practice, the difference in the time it takes is minimal. Kids don't get enough practice anymore. Teachers are afraid of homework.
@@christianrapper You can skip turning them into mixed numbers for addition.
@@christianrapper I never did that for addition. It seemed like doing a detour. If I had to absolutely show everything that was happening to the numbers, I would have expanded like this: (see next line)
2-1/3 + 3-1/4
= 2 + 1/3 + 3 + 1/4
= (2 + 3) + (1/3 + 1/4)
= 5 + 1/3(4/4) + 1/4 (3/3)
= 5 + 4/12 + 3/12
=5 + (4+3)/12
Etc… Being this anal about showing the steps came in real handy much later in algebra when keeping track of variables.
@@hotjanuary exactly why we teach it in such detail. Supposed to make it easier in higher math.
Wow my grade three and four teachers were just so enlightened. My wife is a high school AP maths teacher, and you absolutely do no want to know what she thinks of your amazing maths "tricks" that are literally taught to every child in Canada. I can just imagine you floundering with matrix algebra and calculus. I somehow graduated in electrical engineering and computer science without your help whatsoever.
My calculations have improved, thank you.
This is how I was taught to do it & I loved math.
Hate to tell you this, but your method is what I learned in the USA school system in 1963. Doesn’t matter though, presently in California and Oregon you don’t need to be able to read or do math to graduate high school.
Ty!!! My son is so struggling & your a miracle to us🌹🌹🌹🌹
wow...thank you! I got messed up in math when they started teaching “new math” when I was in 5th grade a million years ago....and I never got math after that. Teachers would explain only ONE way...their way, so I really hated math...but this was so easy and I got all the answers correct. You now have a new subsciber! I guess it is never too late to learn.
I just started uni and this is how my teacher showed us today. I was useless at school. Didn't listen to a word so God knows how I was taught.
Well ask the school to change the teacher. First calculation is 2.(1/3)+3.(1/4), the result should be 17/12 and not 5.(7/12)=35/12, use a calculator if you need a better proof than me
Oddly enough, back in the 70's, this is how my second year maths teacher taught us to handle fractions :D. Thanks Mr. Stepac! (apologies if I spelled your name wrong, it has been about forty-five years :O).
Its Math not Maths. Science not sciences
@@zefrum3 :grins: Perhaps you should learn to speak English; after all, it is an abbreviation of the word Mathematics ... there is no such word as Mathematic :p. Fear not, I have this conversation all the time with my American missus :)
@@dallassukerkin6878 perhaps you mistyped? I didnt speak to you, I 'wrote' to you. And I never said there is a word Mathematic; I simply juxtaposed Mathematics with Science to show the full words suffix do not lend to the abbreviated having the same suffix because the full word suffixes are not plural.
@@Chrysaetos3 do they call them Maths Teacher? Its still incorrect as from what i can google from ;-) Math as an abbreviation existed in typed literature before Maths did.
@@Chrysaetos3 do u say Scis or SciencesTeacher? I dont buy the grammar changing do to the distance of the Atlantic separating Anglo-Saxons and our language; nouns sure but not grammar, especially in our age of information
You know out of everything back in school my teachers always called me dumb for trying to do it this way and they would always ask how I got the answer so I showed them the steps. Yet they paid it no attention and they did it the way they were taught and still got the same answer but by doing that they added one or two many needed steps. I just found it easier for me the way you’re explaining it through step by step. It wasn’t until I was older that they finally said yeah this is way easier I should’ve listened to my A student in the class. Ohhh well I’m just happy it finally sank in and they were able to take less strain on their brains.
Thank you so much. I was always so intimidated when it came to math. Thanks for the help !!!
This is exactly as I was taught in grade 3 about 55years ago. I did not know there were other ways.
I would have been so much better at math back in elementary school in the early to late 90s if I was taught this!
This is essentially what they taught me in the 90s....
Wow! Way quicker!! That’s useful for checking your work because teachers don’t want just the answer, they want the whole solution. So while it won’t keep kids from having to learn the hard way, it will help them o check their answer. Thanks so much! Will make sure my kids learn this asap as my son is just now getting into adding improper fractions and my daughter did it last year but never quite grasped it entirely. :)
if this man was my principal the school year would be 3 months. keep up the tricks!
This is the way I was taught way back when. I can see Mrs. Chamberlain writing it on the chalkboard now.
Mrs Chamberlain did not stooge you!
@@tecmath neither do most teachers, Troll.
You could have just made a great video instead of, for some inexplicable reason, bash teachers for something they don't do.
It's a scummy thing to do.
This was how I was taught in my Engineering Mathematics whilst doing my HNC Electronics in the late 90's. It's never let me down thanks to Mr Lock at Bucks College of Higher Education.
thank you
for taking time to make this, good job
Enjoyed the video. Thanks Tec.
That’s exactly how I learned mathematics in America.
Well, when you and I were in school. Who knows what they’re “teaching” kids with “common core” these days.
This is grade 6 level in school today
@@TerryBradstreet I learned this in 5th grade under common core. Ok boomer.
@@theodoredumas4946 No need for the boomer is there?
@@jkoenig2677
😞. We began fractions in the 3rd grade, and continued with complex into the 4th. I’m not sure how to feel about the “new school” teaching, but I felt saddened when I read your comment.💙
Is it weird that, despite being taught different ways to do this as a kid, as an adult, I want to just turn them into a number with a decimal? Lol. 🤷🏻♀️ I almost never use fractions in real adult life, but percentages and decimals are super common. Even with cups and measurements, I think in decimals.
Yes thought so as well.
Until I started BAKING.
End results, SMILING FACES, full of Goodies from Heart n Hands, to Hearts n Hands.
NOTHING BETTER.😉
Even if you are in baking there is no point to fractions used as a mathematical method... Think about it, why would you need to have a fractional answer to a bunch of fraction related numbers when you can just list the total numbers in a single unit?
Not 2 and a half plus 3 and two sixth pizzas, but what about 44 slices of pizza?
Knowledge can become redundant or outdated to new norms.
I did this as decimal as well added 33.3 and 25 to get 58.3
@@dra6o0n baking is different though. You have to measure to follow a recipe and you are limited to the sizes of your utensils. Try halving or thirding a recipe, decimals will take you to a confusing conclusion. Unfortunately most use volume as a measurement instead of weight as I would love to just weigh all the ingredients and use decimals that way
For most applications it's fine, but when you're working with precision, outside of a base 10 system, fractions do give a far greater precision than a rounded decimal. For most use cases the precision isn't needed though, so it's preference at that point. I'm a machinist, when working with imperial measurements you'll get greater precision with fractions up to a point. When working with metric or base 10 type measurements then you can easily work in decimals to solve for any degree of accuracy. I mention imperial because I mostly work with antique clockwork type items (music boxes, watches, clocks, mechanical cameras, etc) that were built in an era where imperial was standard.
Great advice - could figure answers out straight away. Nearly 50 years old though and don't think I've ever needed an opportunity to use it 😀
I am soooooooooo bad at this stuff but if I had you as my teacher back in the day I would have learn all this thanx you have made my life easier just by what you teach me in this video thanx
