Lol this guy and the mantissa. When he laughs about it, he makes me laugh.

If you're not a teacher, you'd make an excellent one. Why do i never get teachers that can explain things clearly and simple like this?

[@vegassims7]

I have never loved math, but if you taught it to me, it just makes total sense and is not so imposing and / or overwhelming to me. Thanks for having this channel.

[@tdewitt451]

@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.

[@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)"

[@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!

[@craftyfood_lover1762]

His comment section in all of his videos are like the MOST positive comment section in the literal history of KZbin

[@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]

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]

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

[@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.

[@tdewitt451]

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

[@Vaalarie19]

i hope you get everything you want in life. i cannot express how grateful i am for these videos. thank you.

[@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! :)

[@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!

[@tdewitt451]

yes, but i call it unit conversion. so watch my videos starting with "converting units with conversion factors."

[@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

[@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]

no, the way i do it in the video is right. if this is confusing for you, watch my video called "add and subtract with significant figures," and message me if you still have questions.

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.

[@erikmachado4489]

EXCELLENT! This is by far the best explanation I have seen. This what a truly great teacher looks like.

[@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

[@shweta7925]

@dawood awan r u from us?

[@prabhjotgill3371]

do you think you could do a few more examples on scientific notation and significant figures while adding or subtracting?

[@tdewitt451]

no. look at the numbers we start with : 2 sig figs in 2.0, and 4 sig figs in 8.330. we round the final answer to the smallest of these, so it should have 2 sig figs. why do you think there should be 3 sig figs in the final answer?
