    I have been teaching 8th grade math for 5 years now and your videos are by far the best resource I've seen for breaking down what scientific notation is, how to write numbers in scientific notation, and how to connect knowledge of exponent laws to perform operations with scientific notation. Keep the videos coming!

    I am an old person and trying to help my grandchild with schoolwork. Math was never my best or anywhere near best subject. We have watched multiple videos how to do this and there always seemed to be a hidden question that wasn't answered and we would get more confused. Your video broke this down to an absolutely easily understood concept. We now know how to do the exponents including the negative ones the correct way and WHY the exponents were added or subtracted instead of multiplied or divided, Thank you so much, We subscribed. We will definitely be looking at your videos first, THANK YOU.

  • @ashleydavis2355

    I appreciate all of the videos I've watched of your lessons, so far. Reading how to do this kind of thing in a Chemistry textbook is difficult for me. I learn much better by observing, step by step, how each problem should be solved. Thank you! You are a blessing for Chemistry students, such as myself!

  • @im2awesome2die
    @im2awesome2die 8 ปีที่แล้ว

    I used to watch your videos two years ago when I was in Chemistry. Now I take Environmental Science and I had to review over scientific notation. This is a nice throwback to the old days of watching you. Thanks for the help once again :)

  • @tdewitt451
    @tdewitt451  13 ปีที่แล้ว +1

    @rafaeldelaflor i think the video you want is called "scientific notation and significant figures (1.7)" the video called "scientific notation and significant zeros (1.8)" may also be helpful. if those videos don't help you, send me a message with some examples of the type of problems that you would like me to explain.

  • @tdewitt451
    @tdewitt451  13 ปีที่แล้ว

    @CKYAlliance32 do it from left to right. first do the multiplication, then take the answer to that and do the division. since the mantissas are 8.2, 9, and 2, your final answer should have only one significant figure. does that make sense?

    i have a lot of videos on scientific notation with negative exponents. i talk about them in this video. but you probably want to start with my video called "scientific notation introduction," and then you can watch "scientific notation practice problems," and then "fixing incorrect scientific notation."

  • @tdewitt451
    @tdewitt451  14 ปีที่แล้ว +2

    @RedWOLF4Life96 if you're multiplying, you always ADD the exponents on 10. if you're dividing, you always SUBTRACT the exponents. it doesn't matter if the exponents are negative or positive: you know how to add or subtract negative numbers, right?

  • @souflotv
    @souflotv 11 ปีที่แล้ว +5

    when you multiplied 2.12 by 3.58 what did you do to get 7.59 ? im asking because when i multiplied my answer i got was 7.5896 so i was wondering, did you do some rounding off some where ? thanks

    • @nicoleb4984
      @nicoleb4984 3 ปีที่แล้ว +5

      He said he rounded them to the first three numbers. So he rounded 9 and then rounded 8, which got him 7.59 (i know its been 7 years since you made this comment but just putting it out there for other people to know)

      when ur 3rd digit like in 7.5896 , then 8 is rounded up to 9 cuz it was greater than 5 . If it was 3 or 4 or something , it wouldve been 7 only i think , Kick me if im wrong and also feels good to answer a 8 year old question

    • @shaiofthehighlands5792
      @shaiofthehighlands5792 4 ปีที่แล้ว +7

      When you move it to the right, the power of 10 becomes smaller, it means you move one digit away from the decimal. That is also the same as -2-1=-4 based from the rules of integers. That's why the power of 10 became -4. I hope that helped.
