[@HuntingtonTranStudentEHS]

This video helped phenomenally more than the one my AP chem teacher gave us to watch. within 15 seconds of watching, my main question had been answered, instead of waiting fifteen minutes for the yapper in the other video to get to the four points that didn't help with the assignment at all. Thank you for making this!

@yeedust watch my video on "scientific notation: multiplication and division." learn how to do that. then come back to this video and use significant figures in your calculation. your problem is no different from the ones i talk about in this lesson. use the significant figures rules to round.

[@juliehayes15]

I saw an hour long seminar on Significant Figures and didn't understand it all. I've seen your videos and have now got a clear understanding in about 30 minutes. Thank You!

[@jurnicasmith2887]

Dude you have no clue. I had a Chemistry test I had to cram for and you saved my life! Glad my teacher recommended you.

[@emca1597]

Holy shit! I never thought it was this easy thank you. you saved me man. the way my teacher teaches is so monotone and boring you'd fall asleep but thank you, your a life saver

[@DrFluf]

People like you deserve to run our education system. Thank you.

[@Travii12345]

Why is it so much easier when you explain it , ive actually learned more in the past 3 videos vs 3 weeks worth of class ! Bless you man bless you !

[@tdewitt451]

you want there to be the same number of sig figs in both numbers because you're thinking about the rules for multiplication and division. but the rules are very different for addition and subtraction. in this case, you don't care about how many sig figs in the starting numbers, only where the decimal place is. if this confuses you, you should watch my video called "add and subtract with significant figures (1.6)"

[@Veih05]

You are a life saver!! some professors have no patient and expects that you should already know this because it has been discussed in high school. Well, if you are from other country or you have no money to go to college and it will take a long time to get in this class again of course you will forget!! A lot of professors should be patient and be like you. Also, some other brain just does not like math so why push and rush?? Keep up the good work professor!!

[@BrendaTellez-d1x]

I swear Tyler is going to help me pass my Chemistry class. Your videos are so helpful, I'm glad I found them on the second day of the semester. I was about to drop my class. The tutors that the school provides, are terrible. Thank you for helping me and many others. I have recommended your page to many students. You are the best!

[@TheBurnsb]

You are my hero this semester! I’m going to owe my career all to you. If I don’t pass chemistry this semester, my prerequisites for grad school would be at a stand still and I will never be able to ‘pass go’. Thank for making chemistry digestible and fun to learn. Plus you remind me of my ex, whom I adore, another plus. Just had to say thank you! Hope you are getting paid for this, otherwise i owe you, once I’m no longer a student ;) let you know if i pass this semester...tbc

[@astrowyrm6871]

i hate my physics teacher so much, she just makes us do a few problems and write down definition and that's it. Unfortunately she's also my math teacher :/ I'm glad i found you and other people that essentially saved me

[@mckennanicole9057]

you’re the reason i’m passing science, thanks man

[@tdewitt451]

i talk about this in "scientific notation and significant zeros (1.8)". the point is to show that those last two zeros are significant figures. but it's more complicated--check out the video!

[@TrulyFave]

I've been watching a lot of your chemistry videos and you really make chemistry easier. I'm a visual learner and your videos really help! Thank You! :)

[@tdewitt451]

@MXMGamer good question. i did two videos that will help with this. the first is called "scientific notation: addition and subtraction." the second one is called "scientific notation: multiplication and division."

[@tdewitt451]

@bennemann yes, that is *exactly* what you do.

[@sajisejocelb.2141]

Sir 😢😃U just saved me from the confusion Web of significant figures and scientific notation ,Everytime it used to skip from my brain .......Ur way of style just like I am not studying it feels me as I am playing with those topic that before Ur Your Videos Seems to teasing me......☺ Thankyou soo much sir.(in hindi: Dhanyvaad sir).🙇🙏

I just want to thank you so much!!! I'm doing online learning due to the virus and this has confused me so much, but you made the lightbulb go off!!! I hope you have an amazing life 😄

[@tdewitt451]

because i'm adding here, and there are different rules for addition/subtraction than there are for multiplication/division. you want there to be 1 sig fig because those are the multiplication rules. but this is very important--make sure to learn the addition/subtraction rules and it will make sense: watch my video called "add and subtract with significant figures."

[@tdewitt451]

absolutely right. there are different rules for multiplication/division and addition/subtraction.

[@tdewitt451]

@Eywa355 no, i'm sorry, you're wrong. i think you might be confused because you're thinking about the rules for multiplication and division. addition and subtraction have a different set of rules, which i'm following here. let me know if this still doesn't make sense.

Hi, my name is Eva I'm in the 8th grade and my FSA is coming up, and the teacher told us that there will be a lot of scientific notation in there. I was so scared because I suck when it come to scientific notation (well at lease I use to) but then I found your video and that changed everything. Now I find myself to be good in scientific notation, now all I need to improve in is reflections and transformation. I just want to thank you so much for making these great videos that have helped me out so much.

[@rocketrider1405]

Two memory aids for adjusting the exponent of the 10. Case 1: up. "It was LEFT UP to me to clean the cat barf." (moving the decimal place to the left means increase, i.e., up, the exponent on the 10. Case 2: down. "The fire hall is right down the street from me." Moving the decimal point to the right means you decrease the value of the exponent on the 10.

[@souperman6406]

Tylor Ralph remember that when you add/subtract you take the least number of decimal places, not least number of sig figs. 9.2 has 1 decimal place, so after adding the numbers your answer should have 1 decimal place.
