My professor should just play these videos in class on the overhead projector. I've learned more in 30 minutes from these videos than the 2 weeks I've been in class.
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.
@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.
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)"
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!
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
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! :)
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
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 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
@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.
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!
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 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 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 😄
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?
Thankyouthanksyouthankyou! I've watched almost every single one of your chemistry videos. And now I'm actually stoked to pass my chemistry exam tomorrow!
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!
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!
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).🙇🙏
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 🙏
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!
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.
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!!!
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?
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?
Hey Tyler, I have one question about the final answer. Why are we ending up with 3 significant figures when the portion with (9.2x10^4) on has 2? I ended up with a final answer of 1.1x10^5 assuming only 2 significant figures were needed. Thanks for the help!
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.
Dude, whoever you are, live a wonderful life you literally saved my life with your videos
Ameneth lol
HAHAHAAH-
lol hahaha
I agree I am literally having an exam right now
Simp.
If all my teachers were like him I'd be happy to go to school
ikr
me too and I got a+ because of this guy
For reall
But if your classmates are annoying!😂😠
Me too
My professor should just play these videos in class on the overhead projector. I've learned more in 30 minutes from these videos than the 2 weeks I've been in class.
You're god dam right.
Say my name
Agree. How I feel about chemistry 112 right now.
Professor? I'm learning this in 8th grade
The real question is why are you guys learning about sig figs in college...
Lol this guy and the mantissa. When he laughs about it, he makes me laugh.
Same....
I didn't wanna laugh but when he laughed I laughed
Same
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?
propbally becuz there aint one teacher that will go slow and take time for you thats where youtube comes in handy lol
Because some school's just are too cheap or can't afford an awesome teacher.
@@lmnop01 ✔️💯
because teachers are not compensated for their hard work and ability to teach.
@@Vanessa-fp8db not cheap. The government don't set aside the correct budget.

yes, but i call it unit conversion. so watch my videos starting with "converting units with conversion factors."
His comment section in all of his videos are like the MOST positive comment section in the literal history of TH-cam

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

EXCELLENT! This is by far the best explanation I have seen. This what a truly great teacher looks like.
i hope you get everything you want in life. i cannot express how grateful i am for these videos. thank you.
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.
People like you deserve to run our education system. Thank you.

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

you’re the reason i’m passing science, thanks man
do you think you could do a few more examples on scientific notation and significant figures while adding or subtracting?
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! ✨
Aw His face when he laughed made my heart melt
youre amazing. literally i understood every subject you have taught. kudos to you Tyler!
Awesome job on communicating this stuff so clearly. Absolutely perfect.
I just passed a college quiz thanks to these videos. Thank you, they are very helpful!
WHEN I TELL YOU YOUVE SAVED MY LIFEE, not the hero we wanted but the one we needed
Just watched a ton of your videos and am super glad! I found a chemistry go-to!

Why does he keep giggling whenever he says Mantissa??
cuz it sounds like man testicle. Just kidding.
Phanteus lol
Phanteus no, more like some guys do that sort of thing when saying something that strikes us as funny.
Because he's awesome
Lmaooo ikr
Thank you so much. I've been watching your channels and they have been helping me understand so much better. Thank you!!

You have made my Chemistry Class so much easier I Love Your Videos
Ive never learned so much in 8min it usually takes me 3 hours at my school thank you so much ill recommend this to my class mates! :)
the way his face lightens up when talking about chemistry, it is absolutely amazing
Just started chemistry in college this year. HUGE help! Thank you so much
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......☺

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 🙏
Man your video quality is getting better n better I cant wait till I see you in 2015.
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 and examples are very easily comprehensible! I appreciate it so much! Thanks man :)
This teacher makes me give my chemistry problems a evil smile >:)
4:37 "now my answer is incorrect" I was like whaaat? hahaha
lol same! I was like well thats not good
He said "Now my answer is now in correct scientific notation."
Timothy Dyck Gee thanks, I never figured that out.
Sanjay Malhotra 😅
"well thats not good"lmAO
That was the best I've ever had it explained to me. Thank you. I think I now get it.
I find it satisfying watching and hearing you write on the paper with that marker.
IM DOING A PRESENTATION ABOUT THIS TOMMOROW...OMG THANK YOU SO MUCH FOR TEACHING ME NOW I CAN PRESENT IN FRONT CLEARLY AND SIMPLE.
Excellent!!! Thanks for taking the time to put these videos out.
Thank you so much ! All of your videos have been extremely helpful to me! Wish I saw your channel earlier!

Watch it, my mom's name is Mantissa.
@dawood awan r u from us?
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!!!
thank you men your videos helped me a lot.. I needed this for circuits and physics
Thank you, you are the best chemistry teacher ever
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
Thanks bro, you literally saved my tasks with your video.
Thanks for making this so simple! It really helps!
thank you so much. I enjoyed all your 7 videos and learned a lot.
God bless you. My class just started and i think I'd already be failing with out you and your videos
great videos, very concise and clear
I have chem 11 final next week and your vids helped me so much
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?
Thank you. Thank you. Thank you. You have no idea how much this helped me!
thanks so much, u help a lot, tons of student pass the chemistry because of you.
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?
I love your videos so much, they are complete life savers! ♥
Thanks, so much for this video it has taught me a lot with significant digits and I just started basic chemical science this week :)
great lessons! this helped me out a lot for my chem exam

I love how he can't say the word 'Mantissa' without giggling a little XD
Thank you so much Tyler Dewitt you saved my life and my chemistry grade 👏👏👏🙌🙌🙌🙌
you are the only reason for what I have confidence in science.
This math bro be lovin the mantissa, I wish I could buy you a mantissa for christmas cause I owe you big time my G!
Thanks. You teach about 100 times better than my chemistry teacher
you are juzzz awesome sir!!!
Thanks, this helped me A LOT. Now, I just need a video on finding conversion factors.
