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.
@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.
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.
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.
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.
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!
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 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!
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!
@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.
@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."
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! :)
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
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."
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!
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
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
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
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!!
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 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!
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 😄
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! ✨
Thank you so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so much, I knew it wasn’t that hard I was just tweaking over my chem hw for no reason
Yeeessss! I’m a sophomore and this was in chapter 3 and I was like what???? And I even went to office hours, but I still didn’t get it. And then tomorrow I have a test on this and I was like I’m gonna fail I still don’t know how to do this, and then I found this dude and I am officially saved😇🙏🏼
Thank you so much! As a 52 year old college student I appreciate the simplicity of the lecture. I have a chemistry test on Thursday and was worried...Glad to say, not anymore!
Thankyouthanksyouthankyou! I've watched almost every single one of your chemistry videos. And now I'm actually stoked to pass my chemistry exam tomorrow!
Tomorrow's my Physics exam...n ur vids r doing a great help to me !! Thanx buddy ! :D ..keep on posting such vids...bcz we ''the Gen-Y'' prefer UA-cam mre than our books !! :P
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.
Thank you so much this is helping me for webassign a ton my teacher got a 34 on his ATC and he cant even explain scientific notation in a week. Again thank you
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?
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.
@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.
Gayatri Devi Donepudi if the exponents are different, you have to move the decimal until one of the powers has the same exponent of the other one. Watch this guys videos on adding and subtracting in scientific notation, he explains it clearly
in his website, it says " A research scientist, high school teacher, and digital content creator, Tyler draws on these backgrounds to develop engaging curricula and pedagogies that foster critical thinking, problem solving, and authentic understanding. Tyler has taught high school Biology, Chemistry, and English at independent schools in the United States and South Korea, and he worked as a project manager to develop new K12 science curricula for the state of Florida. "
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?
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.
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...
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
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.
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

Haha ain't failing, just wanted to make sure I understand everything
physics for me, we dont learn sig figs in chem at my school
Lol I have an 86 but if I mess this test up, it won’t be good
yes, but i call it unit conversion. so watch my videos starting with "converting units with conversion factors."

8 years later and this video is still help. GOAT

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

thanks so much, u help a lot, tons of student pass the chemistry because of you.
that was very useful i must say. the textbook tries its best to make all this hard for us！these videos are so useful. thanks alot

Excellent sir, lots of respect from #physicistskmfindiatv
how do you round to the significant figure if the exponents of 10 are different, and you are adding?
did you get the answer to this?
