thanks for writing the numbers clearly and speaking clearly (without unnecessary words) ... your videos are a great learning (or as in my case, re-learning) tool
@GuitarxxPro 112560 doesn't have 6 sig figs, because of the zero at the end. watch my video "significant figures and zeros (1.3)" and go from there--it deals with decimals and the sort of questions you need help with.
I had to take a test on significant figures and failed twice. It was the first time that I have ever made a grade below a B. I tried to learn it myself and even asked people for help and still never understood the concepts. I was so frustrated, but I have to say your videos helped me to understand them a 100%!
Absolutely fantastic. I hope education switches to fully online because after seeing this I’ve come to realize that schools these days are an absolute waste of time.
before I find your videos I was bored about this lesson,cuz I was not able to understand it even with books!But the way you teach and show at the same time is just perfect also I don't get bored of watching and learning.Thank you so much!
I watched all of your videos on sig fig all the way up to this just to hear about that. I feel stupid since its so easy. I didn't understand the placement of the decimal and where to have the notation be in correlation to it. Thank you sir.
i don't understand your question. i'm taking 7000 and writing it in scientific notation, so the answer is 7.000 x 10^3. do you know how to use scientific notation? if not, i've got videos on that topic: "scientific notation introduction" and "scientific notation practices problems." message me if you're still confused after watching those videos.
I'm currently taking a college course chemistry class & this is very helpful. However since this is my first time taking the class, I have a few questions on a few problems I have here, that you don't go over.....
In your first example What if the answer was suppose to be in one significant figure? Can you leave it at 7,000? And can you put it in scientific notation? If so, would it be 7x10^3 ?
So in the second example you wanted the second number to be the number of significant figures but in the third example you wanted the first number to be the guide for sig figs....so my question is if you have two different amount of sig figs in two different numbers, which one do you use as a guide?
Yo! On the second problem. 1:49 , 112560 isn't a "5" significant figure, it's 6 i guess. =D By the way, why don't you release a tutorial about decimals and different significant figures? For example : 8.08 dm x 5.3200 dm = ? ( I am in a desperate need of this sort of tutorial-) _GxP.
All the videos made sense until the decimal points were moved and there were fractions. Why did the points need to be moved and why did the problems in the end need to be written as fractions? I was a little lost on figuring how to do the fractions.
***** When did he even considered that? I thought its the same, & he's just changing it into different sig fig number, by rounding off according to the equation & using the least sig fig digits for final answer. He did mention that its only considered a sig fig, if there's a decimal & the zero must be on the right/after a non zero. In that case, 2000 doesn't have any decimal. Any zero that comes after a non-zero, without any decimal is not a sig fig. For zero on the left, even with decimal we know its NOT a sig fig, unless its sandwich between 2 non-zero(with or without decimal).
when you convert something into scientific notation, the number (the mantissa, LOL) must be MORE THAN 1 BUT LESS THAN 10. If he uses 10^2, the answer would be 70.00 x 10^2. The problem is the mantissa can't be 70.00, it has to be more than 1 and less than 10. Therefore the correct answer is 7.000 (which is a number more than 1 but less than 10) x 10^3.
+Merlin Alfane I know how to recycle very well. I recycle every piece of paper I use. I maybe use 20 sheets of paper to make a video. When your teacher copies a 10 page test for 20 students, she's already used 10 *times* as much paper as this video, just in one class period, in one day.

9 years later and your videos are still better than my professor, Thank you so much man
why are there better teachers on youtube than my whole freaking School.
I can't thank you enough for making this easy to understand. My teacher is horrible and cannot explain this simple concept. Thanks!
THANKS FOR ALL YOUR CLARIFICATION AN EXAMPLES... I'M NOW KEEN ON PASSING CHEMISTRY 110 AFTER BEING OUT OF HIGH SCHOOL FOR OVER 25 YEARS
@mariomaruf watch my other videos. significant figures and zeros (1.3) and scientific notation and zeros (1.7) answer your question.
Your videos make more sense than my teacher
Man... this is really going to help my chemistry exams. You the man, Tyler!
You are best teacher i have seen in my life. Thanks

After 10 years this videos still now useful for students .
I love you so much. Since 2015 until now! Thank you!
I watched from 1.1 till 1.8 .... really, I think the idea of the sig.fig and the sic.notation will not ever get out of my mind ! .... Thanks a lot.
you became my best teacher ever !!! Be blessed always !!!
so glad i found your channel!your videos are a life savor.thank yooou!
Your videos are very helpful, all of it actually. it made me understand clearly. thank you so much 😊

These vids are so helpful and so much better than my professor. THANK YOU!
Thank you for uploading very well explained and in depth videos with practice problems. Confident these should help with my Chem exam tomorrow.
Thanks so much !!!
It is really nice and I get more knowledge about significant figures. .
Thank you so much for all your videos. You are brilliant.
Absolutely fantastic. I hope education switches to fully online because after seeing this I’ve come to realize that schools these days are an absolute waste of time.
Bless your soul for these videos
Thank you so much for all of these videos, gonna help me a lot on my chem test tomorrow.
THX Tyler for this after 8 years thx!!!!!!!
THANK YOU FOR THE HELP, TYLER!
before I find your videos I was bored about this lesson,cuz I was not able to understand it even with books!But the way you teach and show at the same time is just perfect also I don't get bored of watching and learning.Thank you so much!
this guy came up with an edge case I didn't even imagine.
Thank you so much for all of these videos, without them I would still be lost.
2voceh
we will be so lucky to have a teacher like u.
thanks! all of your videos helped me alot :]
Dude, you are the best.
seriously this this is awesome!
You a good teacher. Thank you
You are an amazing teacher thank youu
Thank you so much I get this now and it's easy and I have a chemistry test today
You are just brilliant. Im gonna ace this quiz tomorrow, TAKE THAT MR DEWOLF.
Lool
Hey, you will be a
Thank you Tyler .
awesome video thank
you so much !!!
Thank you!

wow . didn't know this part . thxxxxx
thank you sooooooo much
i don't understand your question. i'm taking 7000 and writing it in scientific notation, so the answer is 7.000 x 10^3. do you know how to use scientific notation? if not, i've got videos on that topic: "scientific notation introduction" and "scientific notation practices problems." message me if you're still confused after watching those videos.
life saver!
thank you!
Thank you so much
U MAKE SOOOOOO MUCH MORE SENSE THEN MY TEACHER >.<
Nice
thank god
I'm currently taking a college course chemistry class & this is very helpful. However since this is my first time taking the class, I have a few questions on a few problems I have here, that you don't go over.....
THANK YOUUU
AMG THIS IS SO FUN
you are saving my life 😅😅😅😅
In your first example What if the answer was suppose to be in one significant figure? Can you leave it at 7,000? And can you put it in scientific notation? If so, would it be 7x10^3 ?
thanks
why arent you filling in the zeros whilst doing multiplication sig fig? does the rule not apply here?
So in the second example you wanted the second number to be the number of significant figures but in the third example you wanted the first number to be the guide for sig figs....so my question is if you have two different amount of sig figs in two different numbers, which one do you use as a guide?
how about 0.6667 times 1 ??? should be 0.6667 or 0.7 ?
Sir, how can I keep 1 significant digit if my answer is 4567km ? How can I write it in scientific notation?
I guess it would be 4.567 x 10 ^3 Used the calculator to get the scientific number and this was the answer.
Pixelshayan wrong sir
No discussion of using a bar for zeros?
Does .001 or 10^-3 have 1 sig fig?
another chapter on chemistry plz
Yo! On the second problem. 1:49 , 112560 isn't a "5" significant figure, it's 6 i guess. =D By the way, why don't you release a tutorial about decimals and different significant figures? For example : 8.08 dm x 5.3200 dm = ? ( I am in a desperate need of this sort of tutorial-) _GxP.

hey what about to multipication by Pi number ?? i really need your help right now
and i also have a problem with root numbers
@streetmelvin no i just follow you on youtube
@tdewitt451 I figured it out by the time you posted your first comment, but thanks anyway.
It moved 3decimal to the left thats why it is10^3
Is 2.0x10^3 the same as 2.000x10^3 ?
Yes it is
***** When did he even considered that? I thought its the same, & he's just changing it into different sig fig number, by rounding off according to the equation & using the least sig fig digits for final answer.
He did mention that its only considered a sig fig, if there's a decimal & the zero must be on the right/after a non zero.
In that case, 2000 doesn't have any decimal.
Any zero that comes after a non-zero, without any decimal is not a sig fig. For zero on the left, even with decimal we know its NOT a sig fig, unless its sandwich between 2 non-zero(with or without decimal).
when you convert something into scientific notation, the number (the mantissa, LOL) must be MORE THAN 1 BUT LESS THAN 10. If he uses 10^2, the answer would be 70.00 x 10^2. The problem is the mantissa can't be 70.00, it has to be more than 1 and less than 10. Therefore the correct answer is 7.000 (which is a number more than 1 but less than 10) x 10^3.
why does he round the 9 when he has a 7 to the left. Isn't the 9 greater then that would mean that there is no need to round up?
Rahul Avadhanula no
In the first e.g. your answer was 7.000 X 10^3 why shouldnt it be 10^2 or 10^4?? samething in the next examples.
@streetmelvin $52.30 and you got a deal
العرب الي بيحضروا وينكم😭🤍
o_o you keep changing your hair...
@XxXJamminXx jameel do you follow everything i say on facebook
ill pay you 50 bucks an hour to tutor me on chem
I HATE significant figures and their shitty rules .....
please don't use clean sheets of papers learn how to recycle or to use whiteboard
+Merlin Alfane I know how to recycle very well. I recycle every piece of paper I use. I maybe use 20 sheets of paper to make a video. When your teacher copies a 10 page test for 20 students, she's already used 10 *times* as much paper as this video, just in one class period, in one day.
