Thanks for your Help😊😊😊
Oh
@marctyk Lifesaver ❤❤❤❤❤🎉🎉🎉🎉 Thank you
We need teachers that need to know how to TEACH math. All of my math teachers know how to DO math but not how to TEACH it to other people
I abs agree with you!
Omg! Yes
Mine too
I agree 💯
you need to learn better
I just wanted say, I’m thankful for your existence 😭.
😭
I'm an international student and in Brazil I didn't learn Sig Figs. So my CHEM professor taught this really quickly in class and I was totally lost. With this video explanation I learned it. Thank you for taking your time to upload this video and teach many students around the world. ❤️
you're welcome
Believe me I live in the CA USA and my teacher did exactly the same thing. He has a phd in Chem so I guess that he assumes that everybody is as good as him.
Franciele Faria wow you are an international student
Eu tambem tive dificuldades com Sig. Figs na faculdade. Acredito que o professor daqui subentende que aprendemos no ensino fundamental. Eu sempre uso Khan Academy para esclarecer duvidas.
Franciela Faria. You and I are in the same situation. Thank God for this video.
scientific notation starts at 37:30
Annis thank you
thank u
THANK YOUUUU
You are a God send
Thanks!
when you're watching this because college chemistry hits different
amen
Hits harder than covid-19 when you're in quarantine and not in a physical class room and professors are not always available for virtual video chat 😭
I’m a sophomore in High school tho
You said a mouthful chile
@@smith0540 Exactly
😭😭 if there was a way to use voice note on the comment section....I would use it to express my great appreciation for ur help.
You truly are a blessing to us all
Tru Because of this Covid
I wish you were my teacher instead of my real chem teacher. All she does is give bookwork and doesn’t explain it.
My teacher talks like a rap god.
@@bosstommykross9709 same
Is your teacher Eminem?
She sounds like my previous teacher
The person talking is a woman?
Explanation and process is clear, step-by-step, and not rushed. Lots of examples for practice. This really helped me so much. :')
Holy Cow! This sig fig tutor makes it simple. That's the mark of a good tutor.
Wow, im proud I have teached like him😁
i'm taking my first chemistry class as a college student, and you have made me understand concepts way better than my professor. thank you so much!
I appreciate how well this is taught! Clear and at a very comfortable speed to follow along.
Been struggling the past 2 weeks in chem class & watching this video made it all click!!! Thanks sooo sooo much!!!
I'll add my thanks!! This video has really clarified sig figs and how to round answers for different operations. I'm helping my child with physics and needed to refresh my understanding. THANK YOU SO MUCH!
Really appreciate your effort. At the beginning i thought oh 45 mins its too long, but then i watched it all just to get done once and for all with this issue. Thank you.
Nice pic hahahahah and the original is No pool and the 3
I just want to say, You are really smart! I love how you break the information down in such a humble way. God bless you, sir! Please keep up the good work a lot people are depending on you😇
I know 😃
Our chem and physics teachers ever explained this part and will give us to solve.Thank you 4 ur contribution to us..
I wish I had found this video before spending an hour looking for written explanations on google. It's step by step and much easier to understand!
I have been struggling with this for couple days
You are such a miracle
Thank you alot💜
*an international student from Jordan 🇯🇴
GOD THIS IS SO HELPFUL THAN MY 3 HOUR LECTURE IN UNI THANK U SO MUCH
wait u still learn it in uni? i thought it stopped after u graduate
crazy how many comments are like this like wtf are they teaching all of use and why are they overcomplicating it so much 😭
Just awesome work! Read many articles and watched many videos, but none appeared to me so vivid and easily understandable.
Omgg thankyou so much. This topic was so confusing for me and teachers always leave it by giving barely 2-3 examples when there are so many possibilities to the type of questions under this topic. You covered literally ALL OF THEM. Idk what I would do without your videos
Thank you soo much your explanation was crystal clear and really appritiatable finally I learned it . Ur the best online tutor
You're the BEST ONLINE TUTOR I ever had!
You are a wonderful teacher! I really appreciate your use of blue colored lines to contrast (as visual cues) and showing your work step-by-steps to explain.
Thanks :)
Thank you so much for all your help, you are a lifesaver and I value your hard work. You have made it possible for me to understand physics even better than in Uni. I am sincerely grateful.
Many thanks from South Africa, I've been taught this by the teacher but I didn't understand the rules as she explained quickly and made things even more complicated.
You are truly a big help! Everytime I didn't understand the topic regarding to math and sciences, I immediately go to your channel and watch your tutorial. Weird but I really love your voice.
You are a really great teacher! This video (and all your others) have helped so much! Thank you!
Geez, this was so helpful, really. Thank you so much for explaining this so well 🙏 keep up with your videos, waiting for more 😊
Probably one of the most amazing math, chem, science, etc tutorial videos I've seen :DD. I'm actually using most of your videos when I study. Thank you sir for your vids they are great
Last minute reviewing this before an exam it helps me understand it more tysm!!!
This is my practice chanel after i have taken more concept, finally i come here to practice more, thanks👍👍👍
Thank you for breaking it down. You made that much easier than my instructor.
Man you are awesome I have no words to express how helpful you are. I wish you were my Chemistry professor 🙏🙏🙏
Thanks so much, this really helped me understand significant Figures even though they are so hard to get!
Awesome👌Thank you for teaching the operations in significant figures so clearly💜
AMAZING!! Best regards from Brazil. I could not understand anything about this subject until I saw this video. Thank you very very much, profesor, thank you CZcams and thank you internet.
This was a fantastic tutorial. I absolutely loved all the different examples. :-)
This man is the reason why I'm passing all of my classes. I always hated math as a kid because my teachers just really suck at teaching until I stumbled upon this channel and my understanding of math has been strong ever since.
Thank you the organic chemistry tutor!
This was what I needed. You make the work to be more easier than ever
Thank you so much! This was an awesome help for my chemistry homework!
Bro, I just want to say this is WAYY better explained than how my teacher taught me. Literally, it is sad how students learn more from CZcams these days.
This is great. You are better than the video that my teacher gave me!!!!!! thank you so much!!
You're magical and deserve recognition. Thank you! 😊
the explanation was woooowwww.....all the things are now crystal clear....thanks a lot ..

thank you for this, i have a test tomorrow and was having trouble with adding/subbing using sig figs but this helped a ton
I have a test about this in 2 days, I dont know what I would have done without watching this, the adding and subcracting always tripped me up, but i totally get it now thanks to your trick, thank you (:
I just started Chem 100 and I have been SO lost. Thank you x 10000000 for this! This video just made everything click!! watching the rest now!!! THANK YOU!

Thanks alot...you are the best science teacher I have ever heard....If you were my college teacher, I would not be failing science subjects 😭😭😭
Thank you so much, this video has helped me dramatically.
His voice is so calming that it’s not that hard to study also thx for making me pass my test
这么好的视频为什么还会有人不喜欢？why would anyone dislike this video?!拯救了我的化学好吗
This guy's getting me through my chemistry class and math classes
I started my Mathematics channel 5 years before this guy yet the number of subscribers i have is the amount added to his channel per month or less. Legend!
Hi there, how do we determine the sig fig of uncertainty, standard devaition , relative standard deviation and standard error in analytical chemistry? thank you very much
you helped me alot thanks for that most easiest understandable teaching
This is excellent i loved it. thank you so much you deserve more subscribers really thank you soo much
This video really helped me......very much.....and cleared all doubts...... Thankyou sir..☺️☺️☺️☺️
