    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?

    • @tdewitt451
      @tdewitt451  9 ปีที่แล้ว +164

      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.

    • @andorexurix2491
      @andorexurix2491 9 ปีที่แล้ว +70

      +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.

  • @tdewitt451
    @tdewitt451  13 ปีที่แล้ว +5

    @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.

    @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?

    @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.

    @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.

    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.

      @@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.

    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
      @tdewitt451  9 ปีที่แล้ว +35

      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
      @EmperorEarnest 7 ปีที่แล้ว

      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.

Making the beauty of science achievable and comprehendable by everyone no matter what more important in the long run. Great job!! keep going maybe the Big institutions will catch onto your genius insight.

    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.

    • @tdewitt451
      @tdewitt451  10 ปีที่แล้ว +124

      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.

      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.

  • @tdewitt451
    @tdewitt451  12 ปีที่แล้ว

    yeah, i intentionally left that rule out because i hate it, and it's mathematically incorrect. i know that some teachers like to use it, but it was designed for accounting (like rounding numbers in a bank account), NOT for scientific measurements. so if that rule is in your textbook, then maybe you should use it in class (ask your teacher), but i'm not trying to teach it here.

    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.
