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.

[@tdewitt451]

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: kzbin.info/www/bejne/jHLYpJ-PYrqonJY. 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.

[@andorexurix2491]

+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.

Dude made two perfect circles in a row wtf

[@Als1822]

lmao

[@tdewitt451]

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?

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.

[@iiRozzyy]

11 years later , and here I am learning from your videos

[@NoorMohammad-ef9ie]

Same here😎

[@tdewitt451]

@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.

[@dogkfc3]

12 years later and the video is still saving lives

[@NoorMohammad-ef9ie]

Yeah 🙂

[@tdewitt451]

@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.

[@blinky2k2]

...13 years ago. Time flys. Thank you for helping me pass my classes then and subsequently school later !

[@tdewitt451]

[@joselene1884]

My Professor can't teach so I came here

[@tdewitt451]

@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?

[@nostalgiagaming560]

Watching this in 2021. You have saved my chemistry grade with a video you made almost 15 years ago. You the best dude.

[@asiimwen.5027]

what if the two numbers u are dividing do not have the same number of significant figures? ex. 678/23?

[@Rutdog12]

you keep two than i think

You keep watching the video, and go onto Significant Figures 1.2!

Amazing videos. Eloquent, Articulate, and Effective.

[@PublicSpeaking202]

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 .

[@tdewitt451]

@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.

[@JosephJohnson-pu2vn]

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.

[@gorge123A]

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.

[@tdewitt451]

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.

[@EmperorEarnest]

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.
