Don't be confused by Significant Figures! It will JUST MAKE SENSE with this video! An introduction to significant figures. Discusses how to round for multiplication and division using significant digits.
for anyone who has to take chemistry online: i am with yall and we will try to get through this
😔✊
😔👊
😔✊
my teacher doesn't teach us im my own teacher this year :(
It sucks 😔
Dude is like the Bob Ross of Chemistry. God Bless you, Sir!!!
LMAO!
lol
Mama Realtalk lol fr
This had me dead💀💀😂
Bob ross, lockpickinglawyer, and this guy.
My teacher can't teach so i had to come here.
Lol Thats why I'm here
Pranav Nair Thats why everyone is here lol
+Pranav Nair same
Ms Libao
Same here, hurray for the public school system
Honestly, I see significant digits as a major waste of precious time and accuracy. But, school system demands I know it, so here I am.
Yeah I hear you. I used to hate Significant Figures so much. Then I spent some time figuring out actually why they're important. And I made this video, which you might want to check out: th-cam.com/video/VAuslY-Uuf4/w-d-xo.html. I'm not saying it will make you like Sig Figs a whole lot more, but at least you'll understand why they're important. And also the video's decently entertaining.
+Tyler DeWitt I see their importance, but I don't understand why they should be so heavily weighted on exams, that's the only thing I disagree with at this point.
+Tyler DeWitt y didn't u round the the 3 in 3.39 to 3.49
***** Definitely.
I pay attention in class and mt teacher didn't even teach this he only gave us a worksheet
it's always the lowest number. so there's 3 sig figs in 231, and 2 sig figs in 24, right? so you'll round your answer to 2 sig figs. when i divide 231 by 24, i get 9.625, so i'll round that to 2 sig figs, and it will be 9.6
make sense?
You are a life saver ❤
So smart
Yes
Thank you!
High School teachers, college teachers; they do not teach. They expect you to teach yourself. They are only there to give assignments and you have to go figure it out for yourself! I find Tyler DeWitt a great help. He is so much better than all the teachers I ever had in college.
Dude made two perfect circles in a row wtf
lmao
240p, we meet again.
It's been 13 years since you uploaded this video and you are still saving lives.
thank YOU so much! i love to hear that my videos are helpful. good luck in chemistry!
Hey are you still online these days?
Godbless, I believe this saved my honors chemistry grade
Look at him looking boyish 12 years ago! Tyler is the man - I use his videos all over the place in my physics and chemistry classes. The thoughtful, clear, and well structured design of these videos is a fantastic resource for my students!!!
2019 honors chem grade has been officially saved thank you
"You're probably in the middle year"
Nope tommorow is my FINAL EXAM!!!!
1 week ago?
Him:
You’re probably in the middle of the year
Me:
I’m trying to learn chemistry in 2 days for a placement test 🤦♂️
speedrun time baby
i'm glad it was helpful! i certainly do have a second part. it's called significant figures made easy (1.2). i also have tons of other videos on significant figures: you can find them all by searching my youtube channel, tdewitt451
Your the man🙌
high school freshman year, we've been in school for a week, and this is what we learn
Same
@bennemann you're exactly right! the whole POINT of significant figures is to DECREASE the precision of your result, because it was too precise to begin. if both numbers you multiply together have two digits of precision, your final answer can't have more than two digits of precision.
Watching this in 2021. You have saved my chemistry grade with a video you made almost 15 years ago. You the best dude.
12 years later and the video is still saving lives
Yeah 🙂
Yes but what if you are multiplying or dividing numbers with a different amounts of significant figures
we’re screwed
@@kira6260 oh
I m from India
I m a student
How about we make a whatsapp group
It will be helpful I believe
@Sophie Capps-Hawkins where are you from?
11 years later , and here I am learning from your videos
Same here😎
...13 years ago. Time flys. Thank you for helping me pass my classes then and subsequently school later !
I actually watched the video you made "Why are Significant Figures Important" first and then came back to watch this video and it definitely helped out a lot .
2018 bois?
HipisterPanda yup
Yaas
i'm watching this video in the year 2002
Yaaaaaaas
SQUAAAAAAAD
I really don't like this. But I am forced to learn it.
You too?
no, you chose to learn it.
Hankdatank12345 Sorry, but where I am, Chemistry is needed to pass high school, so sorry for choosing to get an education
You do not need to apologize for making a good choice.
Hankdatank12345 this is basic stuff that you have to learn during compulsory education. Most people don't have a say in whether they're in education at that age or not.
Hey Tyler, great videos. I have 10 and 14 years old boys who are now addicted to your videos. You really make chemistry fun. Helped immensely to switch their addiction from fortnight. God bless.
12 years later and his vids are far better than any out there
what if the two numbers u are dividing do not have the same number of significant figures? ex. 678/23?
you keep two than i think
You keep watching the video, and go onto Significant Figures 1.2!
You use the number with least significant figures.
Tyler DeWitt thanks a lot man. My AP Chem. teacher in high school made this harder than I thought it was. She was a really horrible chem teacher.
Asiimwe N. 29
My Professor can't teach so I came here
This video is 12 years old and has just taught me more than my teacher has in the last 2 classes
Thank you for helping this 46 year old through Chemistry. I appreciate your interest from a teacher's view and making it easy and more understandable.
i do the same number of digits first because it's easier. if you have questions about multiple digits, watch the next video, significant figures 1.2
This video is posted about 10 years ago but still helps students to this day. Tysm 💕
@flashing511 here are a few things that may help. 1,600 has only two significant figures (watch my "significant figures and zero" video for more info on that). but remember that i'm from the US, where 1,600 means one thousand six hundred. in much of the rest of the world, 1,600 means something a little less than 2: one and six tenths. in the US, we'd write that number as 1.600, and 1.600 would have four significant figures. does that make sense?
do not stop making a video for chemistry you the only teacher I understand you
This dude has helped me more than school itself
Who needs school, when TH-cam has everything there. :)
Just found you! My professor is new and me and my class are guinea pigs. So grateful for you!!!!
THANK YOU TYLER. I AM STILL WATCHING YOUR VIDEOS FROM THE FUTURE .
This 2009 video is more useful than the one my professor posted in 2021.
Everything has improved except our stupid educational system.
Who is here on 2023 to see how the legend started his journey
Tyler, I'm a High School Chemistry Teacher setting up to make online lectures for my students. I've used a lot of your videos (Thanks tremendously btw) and had a question about what equipment and presentation hardware and software you use. Any tips as well?
Thanks again, really appreciatethe videos as do my students!
Hello sir
May i get your number
I m a student from india
Please sir
Your whatsapp number 🙏
You taught me more in 7 minutes than my teacher could in a whole class.
Gonna watch 2 hours worth of your vids for Density, Sig Figs and Metric Conversions because my science teacher is very bad at online stuff.
Amazing videos. Eloquent, Articulate, and Effective.
For my chem test, I got every calculation right but I still got a 61% because I didn't round the numbers properly
Chito surumi I know that feel.
+Chito surumi I feel you mate...
Imao thats cruel ..... in my school the minimum to pass a test is 50% .... your score would be considerd great if you were here
In my school 60% is the pass mark
Chito surumi that’s why I’m here too. I just don’t get it!!! I doubt my rounding.
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'm a Senior High School Biology teacher but I'm given a Chemistry subject to teach, having a hard time at first but your videos really helped me a lot! Thanks!
I just wanna say I no longer have a D in chemistry BC of these videos !!!!! TYSM
here are two videos that might be helpful for this: watch "why are significant figures important?" and then "significant figures with measurements and counting numbers."
Hey i am from India and you are just too good...i have no words to describe how blessed i am feeling right now..in India students give respect to their teachers by touching their feet....and i just wanna touch your feet....please bless me SIR...
Thank you
@@shivanshjha938 Hlooo I'm too Indian d's too kannadiga🇮🇳🇮🇳🇮🇳
OK. This WAS GREAT! I can't thank you enough. My sister-in-law comes up to me and asks me for help with chemistry. I cringed because it's certainly not my strongest subject. She hands me her notebook and I had no idea what I was looking at. I did a Bing search and found this video and we both understand significant numbers after having watched this series. So, again. Tyler. THANKS!!!
10 years later and your still helping people! :)
What if I have a multiplication or division of numbers with different amounts of significant figures like 324x23
How many significant figures do I keep on my answer?
Jenn M. The least number of significant number is what you consider. So, in this case you take the 23 which is 2 sig figs
Watching over 10 years since the video was posted
@Allison0776 yes! watch my next video, significant figures 1.2. i have a whole series of sig fig videos, you can watch them in order and everything should make sense!
I am doing a tertiary access course @ James Cook Uni in Australia and you sir have just helped me immensly!
Thank you!
Really well spoken, easy to understand and just well done.
I am really learning a lot from your videos and think that you are a great teacher but I don't like that you say "If your smart you probably already know......." Although I do totally understand sig figs, I'm one of the ones that loves sig figs, it just makes my heart sad that maybe someone doesn't get it and now they may feel worse about themselves because it should be easy and they still aren't getting it.
It's not that deep
S-kun ! srsly
Yupp
I'm watching because I have a test tmr😑....Wish me luck please
EDIT: GUESS WHAT!!!! I PASSED MY FREAKING TEST .... Thank you so much for this helpful video 😊💜
Patriot9827 Thanks bff💜💜😁😁
Kaira Castro good luck
OH MY GOD THANK YOU! my chemistry teacher is terrible! she literally doesnt teach anything, just gives us packets and tells us to read it.... and then she gives us a test and we all fail! this made sig figs look so easy! thank you!
First time in your site Mr T.D I think your method of teaching is beginning to change my hate for chemistry. You are awesome Thank you.
00:01 dat moment when you rip bong and then remember you gotta do a chem video
this is better than my maths class
i understand your question, but 1,600 only has two significant figures, so you don't have to worry. zeroes at the end of a number without any decimal places (like the two zeros in 1,600) don't count as significant figures. you correctly said that the answer could be reported as 1.6 x 10^3, and that's just a different way of writing 1,600. you should watch my video about zeros if you're confused about which zeroes are significant and which aren't.
Thank you !!!!!!! You are my hero . I am having a test on Monday and I had no idea how to do this.
Thanks Tyler, Jesus really appreciates all of your help.
Significant figures seems to be the only thing I’m struggling in on my chem quiz!😫
my college professors weren't as clear as this dude is. Bless you Tyler Bless you!!!!
Bro you are a life saver thank you so much now i can stop worrying for my exam when i see significant questions,
Wish me luck for my test tomorrow
2019 GANG BABY cause my teacher cannot do his job right so I'm here
It’s been 13 years and this man is still saving lives. Not only lives but my grades
@swiitiichiil do you mean that 1.50 is what your calculator gives you, or 1.50 is what you want to round to? if it's the calculator, it might have to do with what kind you're using; i'm using a TI-83, which spits out many numbers after the decimal. if, on the other hand, 1.50 is the number you want as your final answer, that's not right, because the zero at the end counts as a significant figure (watch my video on zeros), and you can't have three significant figures in the final answer.
My chem teacher brought me here, I have to watch all 10 videos lol
+Unlockerlocker Unlockme? Nice screen name.
God bless you Tyler 🙏🏿 #blessed
None of the teachers or videos were able to explain the purpose but you did👏
I needed this.my chemistry teacher was coming up with the most complicated explanations for something that seems pretty simple.
Who is watching this in 2021.
2019😂
2020
Damn I was 3 years old when this came out and now I'm just seeing this in 2019! And I'm 14 years old.
@josh3367 good question. just because it's 6 doesn't mean it's a "counting" number. if it's 6 apples, then it's a counting number (infinite sig figs). if it's 6 feet, it's a measurement with one sig fig. 6 people, counting; 6 pounds, measurement. make sense? here, i just want to show the basics, so i'm doing sig fig rules with all numbers--i'm essentially assuming that they're all measurements.
props to this dude. he got me through high school chemistry. Currently in college and back for more man. If anyone needs help this is the channel to go to!
Wow!!! THIS IS VERY EDUCATIONAL
Wait..........let me just do something

Day before a test squad wya
@TheIkitta if that already makes sense to you, go for it. i talk more about that approach in my video "scientific notation and significant zeros (1.8)."
bro this guy is the best teacher in the whole world
Agreed. He's the one who got me through Highschool Chemistry
who learn this topic in 2024 ❤❤
Some of these information is wrong. 5 is a tricky number when it comes to rounding. For example, if the preceding number is even then you would have to round down. However, if the preceding number is odd then you have to round up.
There's a lot of confusion about this. That rule with the even/odd rounding thing was designed for accounting, for rounding amounts of money. It's actually called the "Banker's Rule." But we're not doing accounting or money management here, so those rules are actually incorrect to use with science. Some teachers tell students to do the even/odd rounding thing, but they're teaching it wrong. The Banker's Rule should only be applied to accounting and money calculations, not to scientific measurements.
I agree with the rule of 5 in rounding off numbers in terms of its preceeding number. That is what I am doing in my scientific computations. It has less error. But in fairness to Tyler DeWitt, your videos are awesome.
@Untravaersil
If you have an area that looks roughly like a square and the sides measure roughly 6 ft each, then yes, the answer is 40 sq.ft.
However, notice the emphasis on "measurement" and "roughly".
If instead you measured the sides with a higher accuracy of 6 ft 0 in each, then the correct answer is 36 ft.
If you didn't measure at all and 6 times 6 are exact integers (as you're doing a problem in math class), the correct answer is 36.
Woah it’s crazy how far your channel has come- watching a video from 9 years ago is crazy considering we have to watch your more recent videos for chemistry all the time. Kudos to you !
Wow this video is OLD!
+OfDaSouth yeahhhhhhh!
Yup
OfDaSouth And ur comment is too
right? it's straight out of the TV my Grandma grew up with. It did help me get significant figures tho
@@michellebuswell9586 The video was made in 2008, so your grandma must be a little bit older than you and your mom must be the same age that you are. There was no such thing as TH-cam when your grandma was a kid. It is just a math video. The guy in the video is not that old. The made a simple and basic video to help other people.
anyone in 2020? Yeah online school is rough and this video really helped
Tell me why this guy is better than all my math teachers combined
Thank you so much. You have saved me about 20pts on my quiz and much more in the future.
As soon as an instructor says the words "if you're smart..." I immediately discredit everything they say before and after that statement. There is no need to be pompous just because you know a little something that others don't. Most especially when those "non-smart people" are looking to you for help.
I'm sorry that felt offended by that comment. I said that without thinking, and I understand why it could be frustrating, and I wouldn't say anything like that again. However, I *deeply* and powerfully resent that you accused me of being pompous. I have spent literally thousands of hours of making videos-for free-to help people with school. Shame on me for making a careless comment. Shame on you for attacking me when I'm spending my life trying to help others.
Tyler DeWitt Agreed
dracophyle Quit your crying, it's a FIGURE OF SPEECH, he obviously said it in the spur of the moment, he CLEARLY wasn't making a value judgement, he's clearly saying something that's the equivalent of "now if you're really following what's going on, you'll notice that, etc etc," or....." now if you're really following along and catching what I'm saying, you'll notice that, etc etc." INSTEAD, he simply chose to say, "now if you're smart." Guess what? If you're smart, you may quickly pick up on which of the three statements one would be most likely to say off the cuff whilst recording a video. Only if you're smart though. Good day.
butt hurt
I agree...
Hm. I'm pretty sure this guy looks like a mix between Samwise Gamgee from "The Lord of the Rings" movies and Riley Poole from "National Treasure"...
Oh my gosh, yes exactly 😂🤣
He is the best at explaining chemistry. Thank you!!!!
your last lessons was 4 years ago, seems like you came back 4 months to help us with this 😅😅 thanks
13 years later here I am 😂
Me too😅✌
2018?
Tyler, can you writer a book that details how to develop the art of teaching.That will be one of the greatest gifts for mankind.
How old are you now sir
This video was when I had 2 years old
How many generations have get help through here?
I am a basketball player but this guy is making me feeling about studies more
