Scientific Notation: Multiplication and Division

[@JessicaLangston870]

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.

[@jadepodboy8437]

❤😅❤😅❤❤

[@Grannyrat1]

PLEASE CONTINUE MAKING VIDS LIKE THIS! You are literally saving me in chemistry. The teacher doesn’t explain ANYTHING!!!!

[@sharkmafia7038]

Same here

[@luannsilva6945]

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!

[@aspirate]

Good point. xD

[@xp_torq116]

[@jalonconway7816]

SPENCERDC this is chemistry for me

[@lae.mp6772]

That is so true this is so in depth

[@cynthiadrott-puett1762]

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.

Why can't all the teachers in the world be like you?? Thank you so much!!😭 you saved my life!!!♡

[@Max-el7zd]

You are literally a GOD of explaining things. Your abilities to make everything make sense is crazy.

[@ezmah2283]

this guy explained it better in a minute and twenty seconds better than my math teacher could in an entire block.

[@tdewitt451]

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."

[@storem1000]

I'm studying electronics and you just made things much easier for me. Thanks for taking the time to help others learn.

[@dhanedelapena21]

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!

[@tdewitt451]

@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?

[@AMAN_GAMER728]

Watching this video is perhaps one of most important things I did for preparation for my exams.

[@PublicSpeaking202]

This is so sad that so many professors do not know how to break down Chemistry like this guy. Tyler DeWitt you ROCK!

[@tdewitt451]

@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.

[@deltaforce4477]

Our KZbin 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.

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.

[@abbyspark3937]

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!!!!

[@smooveoner8823]

Im having a hard time with these types of problems in school. I really needed this. Thank You

[@desireelawrence4353]

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!

[@JoseCamacho_Tujaycee_2JC]

fire my teacher and replace her with that smart guy.

[@KaspenPlayzz]

Imagine if your teacher saw this comment

[@lavendelelv]

Thank you!! I missed class i was sick! but you caught me up! :) thanks again ~~

[@Saranghae197]

Wow, this taught me more than a whole hour of class did. Thank you very much.

[@IsaiahRoe]

You are a fantastic teacher my friend. Took a concept that completely baffled me and made it seem like a walk on the park.

[@anasings5463]

I LOVE YOU SO MUCH YOU DONT UNDERSTAND HOW GREATFUL I AM FOR YOU YOURE CHANGING THE WORLD MY GUYY

[@LotsOffGlitter]

I think you meant 3.05 x10^6. You forgot to round the significant figure. 9.72/3.19=3.047. and there is 3 significant figures so we stop at 4 but change the 4 to 5 because 7 is a high number.

[@BigLoNasty]

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.

[@souflotv]

ok my answer was already given in the video , ignore the question about 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!

[@trog6782]

You saved me, thanks man!! My teacher just sped through it without explaining it much.

[@epitomeofhappiness14]

You are so helpful, where my teacher is not. you saved me from failing a test! thank you so much!

[@souflotv]

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

[@nicoleb4984]

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)

[@willrupee]

Damn bro ive seen your vids before 😳

[@queengee5282]

Yes he rounded up to have 2 decimal places

[@arihantjain6646]

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

[@muffiner7970]

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

[@tyecleveland6451]

You just saved my job. this is a real blessing. thanks for being so thorough.

[@deveanaustin7252]

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

[@jameslekejr.4036]

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]

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.

[@LuffyFilmZz]

@@shaiofthehighlands5792 the smaller the number, the bigger the negative number exaple -3 if you want it smaller then its -4

[@historicalnow9241]

I had the same problem too, suddenly I remembered about the bigger the negative number, the smaller the value.

[@evelynsoto7695]

This has made chemistry so much easier he's the real mvp

You just did in 5:30 minutes what my teacher couldn’t in 1:30 hours

[@melodyverde1955]

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?

[@rhondagump1092]

Thank goodness for Tyler DeWitt! His videos are the only thing keeping me above a 3.0 in Chemistry.

[@rafaeldelaflor]

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.

[@crackerbarrel9422]

If this dude did more math tutorials we'd all be ballin.

Hi. I'm a bit confused. When you divided 9.72 by 3.19, shouldn't the answer have been rounded to 3.05 instead of 3.04? Thank you.

[@tdewitt451]

@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?

[@CC-fq8bn]

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

why would 9.72/3.19 rounded to 3 sig fig be 3.04? Shouldn't it be 3.05 as the answer is 3.047 rounded to 3 sig fig? Please help.

[@lizzycute123]

In what case would you do what you do in adding and subtracting scientific notations which is moving the decimal to make the exponent greater. In what case you do that with multiplying and dividing.

[@shandanaiftikhar1960]
