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.

@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.

Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.

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!

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.

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!

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)"

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 !

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

@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.

Hey Tyler my son started watching your videos a week ago before my exam.Your Videos are great and you're the best chemistry teacher ever

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!

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

I am so glad to find these videos! I am going back to school in my 50's and this guy makes it easy to understand! Thank-you!

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! :)

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."

@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."

You just got me to understand something that my teacher took like 2 weeks on and I still didn't understand. But you took like 8 minutes and I feel like a genius now! THANK YOU :D

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

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

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.

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

Thank you for this! This is my topic for my demo teaching and I'm really confused about it but when I watched your video, I already understood it in just 7 minutes. You saved my life brother! ✨

I have not used calculations for several years and decided to get my nurse practitioner (DNP) You provided a great review for my chem class. Thank you kindly!

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

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

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 😄

IM DOING A PRESENTATION ABOUT THIS TOMMOROW...OMG THANK YOU SO MUCH FOR TEACHING ME NOW I CAN PRESENT IN FRONT CLEARLY AND SIMPLE.

Nice, very helpful! I was having so much trouble figuring out the end result number in how many sig figs I would round too and how to start to find my final rounded answer. You made it easy to understand! Thank you for this video! You sound like you really do have a calling/passion for helping those with chem problems. God bless!

Man your video quality is getting better n better I cant wait till I see you in 2015.

youre amazing. literally i understood every subject you have taught. kudos to you Tyler!

@Imahorde to learn how to do this, you should watch my video called "scientific notation: addition and subtraction."

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

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

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

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.

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?

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

I find it satisfying watching and hearing you write on the paper with that marker.

8 years later and this video is still help. GOAT

Just started chemistry in college this year. HUGE help! Thank you so much

what do you do if the scientific notations are different in exponents of the addition/subtraction problems

Awesome job on communicating this stuff so clearly. Absolutely perfect.

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).🙇🙏

So, in an addition or subtraction problem we have to make all the exponents the same. Once we do that and change the mantissas accordingly, we can then go ahead and use the place rule?

Thank you so much. I've been watching your channels and they have been helping me understand so much better. Thank you!!

help, what would the answer by when you round 2.999 ×10 to the 2 power to 2 significant figures?

Just watched a ton of your videos and am super glad! I found a chemistry go-to!

I love you Tyler. I was so sad that I was going to fail my test because I missed a few days of school. Ur the best

I have chem 11 final next week and your vids helped me so much

this was so helpful thank you! I was just wondering: I notice you use lot of paper in all of your videos. perhaps you could use a whiteboard or something to be more (sorry to be cliche) "Eco-friendly"? Thank you so much for your help!

your explanations on scientific notation really helped me master this information for my state exams. Would you be willing to do one on power functions as well?

the way his face lightens up when talking about chemistry, it is absolutely amazing

@tdewitt451 My teacher told me that when doing multiple-step calculations with measured data, one should not round the numbers by taking sig figs into account except in the very final result, so as to not lose precision due to the would-be rounding. How should I proceed then when choosing the sig figs for the last result? Do I scan all the measured data looking for the one with the least sig figs, and use that for the result?

Thankyouthanksyouthankyou! I've watched almost every single one of your chemistry videos. And now I'm actually stoked to pass my chemistry exam tomorrow!

@rachellauren996 good question. sometimes they count, and sometimes they don't. i talk about this in my videos on significant figures and zeros--check them out, and they should clear everything up.

Tyler how about the sig fig in 2.871+0.758? Wer to draw the line?

Amazing thank you so much I wish I could have you as a tutor my teacher makes things so difficult and doesn’t try to explain everything as you do. So appreciative of your videos you will be the reason I pass chemistry 😆👍 thanks 🙏

I'm confused. I have 0.413/9.212x10^3 I end up with 0.045 which has 3 sig figs (like 0.413) but if I move the decimal to 4.5 the sig fig count goes down to 2 because the sig fig 0 moves to the left of the decimal... where do i go from there? how do i make it retain 3 sig figs?

Why is the exponent raised from ^4 to ^5 when the decimal is moved to the left at the end of the 2nd problem ??

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

Watch it, my mom's name is Mantissa.

You have made my Chemistry Class so much easier I Love Your Videos

Thanks bro, you literally saved my tasks with your video.

I have this summer assignment I've been doing for AP Chemistry, and I'm supposed to show my work, but if it's as simple as ignoring the powered number, how would I show my work? Do you know the far more expansive version of solving problems that teachers always try to get across to their students, but fail to, because students are smart, and we find shortcuts? (: Haha. Please help to broaden my knowledge on this though. It seems incredibly easy, however, a problem not needing extra explanation should not be dealt with at this time. My brain is already swollen by all the information I've had to retain this summer.

may I know why you move the decimal place to the left?

What is it is 0.003*10^23. Would it be one sig fig or four??

How is 0.24X10^4 wrong, but 2.4X10^3, correct? Then why not write it as "24X10^2"?

Your explanations and examples are very easily comprehensible! I appreciate it so much! Thanks man :)

Give this guy a trophy. Thank you, sir! So helpful

Thank you so much ! All of your videos have been extremely helpful to me! Wish I saw your channel earlier!

i was wondering for the addition and subtraction...wat if the 10 to the power exponent is different? what would you do???

This was so helpful to me, thank you for posting this! I was struggling with sig figs until I watched this video. Thought I'd let you know it's appreciated and now I will pass my test haha :) Thanks so much!!!

WHEN I TELL YOU YOUVE SAVED MY LIFEE, not the hero we wanted but the one we needed

Isnt the final answer 3 sf with 1.13? shouldnt it be 1.1 according to the other numbers we added?

So does it mean that when we add/subtract is that we will not anymore care about significant figures?

Aw His face when he laughed made my heart melt

Could you talk about "rounding error," please? My professor talked about it, but it made zero sense (in class AND when I saw her one on one). I don't know what it is, and I'm afraid I might be doing it since I feel like I'm doing the questions correctly, but then get marked wrong.

what if when you add or subtract its like (2.0 X 10^3) (4.5 X 10^5) different powers.. how do you make them the same

What if we moved the decimal to the left it will be 10 to the power of 5 right ?

can i ask u abt the last result, why 1.13 x 10^5 but not 1.1 x 10^5? because from “addition and substraction” rule the result will follow the lowest digit behind the comma which is only 1 digit allowed, thank you

Tyler, why is it 7.100 instead of 7.1?? What if in the exam we're asked to put 71 in scientific notation and find the sig.fig.? How should we know what to do?

For addition and subtraction, what if they're not the same?

TYLER HOW WOULD YOU DISTIBUTE THE ANSWERS I HAVE AN EXAM IN A DAY AND THIS IS KILLING ME PLEASE HELP

God bless you. My class just started and i think I'd already be failing with out you and your videos

Great video. Used this to review with students. Do you have a video combining multiplication and division in the same problem? And, with negative exponents?

how about if the exponent in addition are not the same?
