This video made more sense than 6 chapters in my chemistry book. I literally went month's without understanding how to multiply and divide scientific notation. THANK YOU.
I have been teaching 8th grade math for 5 years now and your videos are by far the best resource I've seen for breaking down what scientific notation is, how to write numbers in scientific notation, and how to connect knowledge of exponent laws to perform operations with scientific notation. Keep the videos coming!
I am an old person and trying to help my grandchild with schoolwork. Math was never my best or anywhere near best subject. We have watched multiple videos how to do this and there always seemed to be a hidden question that wasn't answered and we would get more confused. Your video broke this down to an absolutely easily understood concept. We now know how to do the exponents including the negative ones the correct way and WHY the exponents were added or subtracted instead of multiplied or divided, Thank you so much, We subscribed. We will definitely be looking at your videos first, THANK YOU.
I used to watch your videos two years ago when I was in Chemistry. Now I take Environmental Science and I had to review over scientific notation. This is a nice throwback to the old days of watching you. Thanks for the help once again :)
Thank you so much! You just taught me in 5 minutes what I spent years not understanding from any of my professors! And scrolling through your other videos, I can tell that I'm going to be using your channel quite a bit as I do my Chemistry homework this semester.
Thank you very much! You help me survive my online class on General Chemistry, it's my fault because I slept during the class and turned off the camera, THANKS A LOT!
Our CZcams educators like this guy should get paid for making these simple videos, they know how to simplify our math stuff than our teachers do in most math classes these days.
Wow thank you SOOOOOO much!!!!! I needed help with this and this has proved to be very useful and simple than I thought :D Now I get it and can explain it to my friend or send her the link :D THANK THANK YOU!!!!
I appreciate all of the videos I've watched of your lessons, so far. Reading how to do this kind of thing in a Chemistry textbook is difficult for me. I learn much better by observing, step by step, how each problem should be solved. Thank you! You are a blessing for Chemistry students, such as myself!
@RedWOLF4Life96 if you're multiplying, you always ADD the exponents on 10. if you're dividing, you always SUBTRACT the exponents. it doesn't matter if the exponents are negative or positive: you know how to add or subtract negative numbers, right?
Thank you so much Tyler DeWitt! This is mind-blowingly awesome when I already understood every bit of it. Please keep making more videos, because you have a great potential to be a great ChemTeacher on CZcams. Once again, thank you so much. Salute ! :D
@rafaeldelaflor i think the video you want is called "scientific notation and significant figures (1.7)" the video called "scientific notation and significant zeros (1.8)" may also be helpful. if those videos don't help you, send me a message with some examples of the type of problems that you would like me to explain.
@CKYAlliance32 do it from left to right. first do the multiplication, then take the answer to that and do the division. since the mantissas are 8.2, 9, and 2, your final answer should have only one significant figure. does that make sense?
THANK YOU!!! You are a math master, praise your brilliant mind! Thanks for taking time out of your life to thoroughly explain so many complex math processes!
i have a lot of videos on scientific notation with negative exponents. i talk about them in this video. but you probably want to start with my video called "scientific notation introduction," and then you can watch "scientific notation practice problems," and then "fixing incorrect scientific notation."
You are AMAZING. I have never understood math fully until watching your videos. Thank YOU !! Keep this up. You are a genius !!!!!! Even though this is from 2010
Hey Tyler, this last division problem has me confused. You said when we move the decimal to the left the exponent goes down. so shouldn't the right S N answer be 2.67x10 to negative 2?
When you move it to the right, the power of 10 becomes smaller, it means you move one digit away from the decimal. That is also the same as -2-1=-4 based from the rules of integers. That's why the power of 10 became -4. I hope that helped.
Very thankful, I'm just now learning how to do this in science class. I was stumped on my homework, I watched this video and now I understand it way better. Thanks again.
thanks so much for all your videos, my instructor is sooooo bad at explaining things...well, she doesn't really explain, she just murmurs to herself in the front...wish every teacher is like you ! !
Thank you very much you teach better than my teacher! Thank you keep up the good work, and if my friend asks me whats a good math youtube channel ill recommend you.
they "taught" us this in highschool, either they didn't make it interesting like you did, or I wasn't paying attention but I find this relaxing and fun to do when i felt so much pressure in school
when you multiplied 2.12 by 3.58 what did you do to get 7.59 ? im asking because when i multiplied my answer i got was 7.5896 so i was wondering, did you do some rounding off some where ? thanks
He said he rounded them to the first three numbers. So he rounded 9 and then rounded 8, which got him 7.59 (i know its been 7 years since you made this comment but just putting it out there for other people to know)
when ur 3rd digit like in 7.5896 , then 8 is rounded up to 9 cuz it was greater than 5 . If it was 3 or 4 or something , it wouldve been 7 only i think , Kick me if im wrong and also feels good to answer a 8 year old question
2.12 x 3.58 = 7.59 How did you get that what did you add/mutiply to get that asnwer you lost me on that part and i have no idea what numbers you added or mutiplied to come out with that answer
Thanks for being so motivated. I wish you would make a focus video on rounding the resulting figures with scientific notation. From scientific notation to scientific notation and from figures to scientific notation with rounding.
I honestly can't believe i learnt that in 5 mins where in my class i had to legit take 1 hour to "learn" but actually not learning how to do it, PLEASE BE MY TEACHER!

❤😅❤😅❤❤
All the dislikes are from those Math teachers that suck at explaining things
True
And also that is all the teachers in the world
Same
Ya
Orion the Hunter I agree and one of those teachers is my teacher Mr. Herrera
PLEASE CONTINUE MAKING VIDS LIKE THIS! You are literally saving me in chemistry. The teacher doesn’t explain ANYTHING!!!!
Same here
Why isn't my math teacher this clear...?
+WastingFilm because you're chemistry teacher should be teaching you this
Good point. xD
+WastingFilm yeah I'm learning this in math and my teacher is so dumb compared to him
SPENCERDC this is chemistry for me
That is so true this is so in depth
dang this is way better than khan academy
and it was posted literally 9 years ago.. this dude is a genius
-32×10^(-19)=???
How to multiply this ..
I know its answer is -3.2×10^(-18)
But howww...
Yupp

fire my teacher and replace her with that smart guy.
THANK U SO MUCH MY CHEMISTRY TEACHER IS SO BAD AT EXPLAINING STUFF
heycarolina really?
Same
THATS WHY IM HERE TOO but.... It’s more like he wasn’t bad at explaining more like me being dumb.
Same here
same, I couldn’t understand my maths teacher

this makes SOOOOOOOOOOOOO much more sense than khanacademy! Thank you so much!
FR!
lol
THE STRUGGLE IS REAL
frfr bruh
Yeah! I know right???
Why can't all the teachers in the world be like you?? Thank you so much!!😭 you saved my life!!!♡
Thank you so much! You just taught me in 5 minutes what I spent years not understanding from any of my professors! And scrolling through your other videos, I can tell that I'm going to be using your channel quite a bit as I do my Chemistry homework this semester.
No words to fully express how freaking amazing you are! 24 years without chemistry and thanks to you, I understand what I’m doing!!!!
This is so sad that so many professors do not know how to break down Chemistry like this guy. Tyler DeWitt you ROCK!
You are literally a GOD of explaining things. Your abilities to make everything make sense is crazy.
Thank you very much! You help me survive my online class on General Chemistry, it's my fault because I slept during the class and turned off the camera, THANKS A LOT!
Our CZcams educators like this guy should get paid for making these simple videos, they know how to simplify our math stuff than our teachers do in most math classes these days.
this guy explained it better in a minute and twenty seconds better than my math teacher could in an entire block.
Im having a hard time with these types of problems in school. I really needed this. Thank You
Wow thank you SOOOOOO much!!!!! I needed help with this and this has proved to be very useful and simple than I thought :D Now I get it and can explain it to my friend or send her the link :D THANK THANK YOU!!!!
These videos help me so much! I can understand the concepts more clearly than from just reading it in my textbook. Thanks so much!
Thank you!! I missed class i was sick! but you caught me up! :) thanks again ~~

You just saved my job. this is a real blessing. thanks for being so thorough.
Watching this video is perhaps one of most important things I did for preparation for my exams.
THANK YOU!!! You are a math master, praise your brilliant mind! Thanks for taking time out of your life to thoroughly explain so many complex math processes!
You are a fantastic teacher my friend. Took a concept that completely baffled me and made it seem like a walk on the park.
I'm studying electronics and you just made things much easier for me. Thanks for taking the time to help others learn.
Your amazing!! My teacher couldn’t even teach me this and when I watched this video I understood. Thx😃
My math teacher is so confusing and this helped me so so so much. Thank you. This is a lot easier than I thought it was
you're my hero THANK YOU. I couldn't understand this even after my teacher tried to explain many times. Now I understand
i have a lot of videos on scientific notation with negative exponents. i talk about them in this video. but you probably want to start with my video called "scientific notation introduction," and then you can watch "scientific notation practice problems," and then "fixing incorrect scientific notation."
You are AMAZING. I have never understood math fully until watching your videos. Thank YOU !! Keep this up. You are a genius !!!!!! Even though this is from 2010
Thank you sooo much Tyler. I watch these with my 8th grade son who struggles in Math. These are perfect..
Hey Tyler, this last division problem has me confused. You said when we move the decimal to the left the exponent goes down. so shouldn't the right S N answer be 2.67x10 to negative 2?

@@shaiofthehighlands5792 the smaller the number, the bigger the negative number
exaple -3 if you want it smaller then its -4
I had the same problem too, suddenly I remembered about the bigger the negative number, the smaller the value.
Forget about how much the video is old ...but the content present. ..its awesome ❤😊
Wow, this taught me more than a whole hour of class did. Thank you very much.
Thank you so much I recently failed my math test on this and your video helped me realize where I went wrong so I can do better on the retake
I watched all of your scientific notation videos they were all really helpful im going to ace my test tomorrow
You explained that very well, and on top of that, I hope to get all of these types of problems on my test tomorrow. Thank You!
You are amazing! I have watched a number of your videos to study for my exam. Thank-you so much!! You could teach Chemistry to kindergarten students.
You teach a lot better than my actual chemistry teacher.. thanks for the help man
I LOVE YOU SO MUCH YOU DONT UNDERSTAND HOW GREATFUL I AM FOR YOU YOURE CHANGING THE WORLD MY GUYY
I love this guy! He’s helping me soooo much☺️👏🏻👊🏻
You saved me, thanks man!!
My teacher just sped through it without explaining it much.
Very thankful, I'm just now learning how to do this in science class. I was stumped on my homework, I watched this video and now I understand it way better. Thanks again.
You are amazing can't thank you enough for your time making these videos!
Thank goodness for Tyler DeWitt! His videos are the only thing keeping me above a 3.0 in Chemistry.
On my calc I got 7.5896? Instead of 7.59. Am I supposed to do something or is either answer right? I’m not sure
Thank you! You made this so much easier than the way my professor was teaching it. Thank you! Thank you! Thank you!
thanks so much for all your videos, my instructor is sooooo bad at explaining things...well, she doesn't really explain, she just murmurs to herself in the front...wish every teacher is like you ! !
This was great! thanks to you, I can get an A on my Chem test tomorrow!! finally a mathmatician I can UNDERSTAND!!
on question #2 wouldn't it be 3.05? instead of 3.04 because there is three sig figs so it moves 3 decimal places?
Very good explanation. Better than Khan Academy's.
This chanel is a life saver !
thanks for the review, been about 7 years since i have had to do this. knocked some rust loose with this.
This has made chemistry so much easier he's the real mvp
Please make more videos!!!!! You are the wizard of chem.
thank you sm all these concepts in my earlier class were not clear but now after watching this video helped me a lot
I'm learning this in math and it's the exponents that always get me! thank you so much for making it clear!
Thanks Tyler, i needed to raise my grade in school and your vids really helped me study
Ur like a freaking miracle worker, This was SOOOOO helpful
Thank you very much you teach better than my teacher! Thank you keep up the good work, and if my friend asks me whats a good math youtube channel ill recommend you.
Thankyou!!! I have a test tomorrow on this and thanks to this vid, I understand it way better
If this dude did more math tutorials we'd all be ballin.
My Chem teacher just confused me more... Thanks ! You save my life
Hiii sweety
Thanks, my chemistry teacher is sub-par and didn't teach us this, so thanks for filling in the gap!
OMG! THIS HELPED ME SO MUCH!! LOOK FORWARD TO PASS MY MATH EXAM NOW, TOMORROW !!!!
Thank you. You set up these videos in a way that is easy to learn from :)
they "taught" us this in highschool, either they didn't make it interesting like you did, or I wasn't paying attention but I find this relaxing and fun to do when i felt so much pressure in school
Thank you so much, i have a huge math test tommoro and my math teacher is way to complicated. You helped me very much
You are amazing ! You made this so clear. Thank you!
Nice channel, keep it up
You are so helpful, where my teacher is not. you saved me from failing a test! thank you so much!
where do I find these at ?
16x2+102x+77+0 the 2 is squared ?
Thank you so much! It is because of you that I understand chemistry now since my teacher is too dumb and lazy to explain things in detail.
when you multiplied 2.12 by 3.58 what did you do to get 7.59 ? im asking because when i multiplied my answer i got was 7.5896 so i was wondering, did you do some rounding off some where ? thanks
He said he rounded them to the first three numbers. So he rounded 9 and then rounded 8, which got him 7.59 (i know its been 7 years since you made this comment but just putting it out there for other people to know)
Damn bro ive seen your vids before 😳
Yes he rounded up to have 2 decimal places
when ur 3rd digit like in 7.5896 , then 8 is rounded up to 9 cuz it was greater than 5 . If it was 3 or 4 or something , it wouldve been 7 only i think , Kick me if im wrong and also feels good to answer a 8 year old question
thanks soooo much! I have a chem test tomorrow and this totally helped me!
Exactly what I needed. Fantastic. So clear!
2.12 x 3.58 = 7.59 How did you get that what did you add/mutiply to get that asnwer you lost me on that part and i have no idea what numbers you added or mutiplied to come out with that answer
Thank you so so much for these videos! They are SUCH a huge help!
Wow thank you for the clear instructions. You made it easy for me to understand!!
Thanks for being so motivated. I wish you would make a focus video on rounding the resulting figures with scientific notation. From scientific notation to scientific notation and from figures to scientific notation with rounding.
You just did in 5:30 minutes what my teacher couldn’t in 1:30 hours
I am Indian ...... Thank u very so muchh sir really ur vedioes r very helpfull first time completely clear my all doubt s from this topic
is it possible to multiply the one who has a negative exponent and a positive exponent ?
Thanks for explaining this man! It really helped me out
Awesome, this just helped me out review and do part of my AP Chemistry Summer assignment, thanks and God bless!
I honestly can't believe i learnt that in 5 mins where in my class i had to legit take 1 hour to "learn" but actually not learning how to do it, PLEASE BE MY TEACHER!

Thank you so much, I was scared I was going to fail my science test because of these kind of problems. I understand how to do them now!
thank you so much !! only if every teacher was like you ..
Very clearly explained. Well done!
Third and last video These are really useful!
Why couldn't my professor make it this easy?! Thanks you just saved me!! :)
