    You need a freaking Academy Award for this amazing video. Not only did you bring up Googool, you mentioned your lovely wife and her attention to detail about adding a zero in front of decimals... I have clarity now! Last night I dreamt that the whole world had scientific notation as directions. My Ram truck dashboard read: "Speed six to the 10" and my Amazon orders was 1 to the negative tenth and I owed PayPal money in the negative tenths and so on. Today I will just ride my fat tire bike and forget about it for a while. Your cursive writing is APLUS... Like clouds in a world of ordered chaos. What will your Academy Award speech be about.? ? "" ? I hope world peace, because you are the only way out of this mess EG summation, No ads, No ads, clarity, nice voice, and you are helping some girl in Afghanistan bring about peace in her time. This can be proven with scientific notation Zero to the negative tenth times one is at least a chance.

    shouldn't 0.005 x 0.0008= .0000040(after moving the decimal 7 places to the left starting at the zero after the four) which equals =4x10^-6 (same as my calculator) ?? because we always go to the first non-zero number ??

  • @chrishuckeba619
    @chrishuckeba619 9 років тому +1

    Your videos are great, but I have noticed that you usually start off examples with small numbers. Like x to the first, or x to the second or third, then you jump to higher examples like x to the 100. But hell, beggars cant be choosers when it comes to a library of pretty much everything down the line.

    Would it be 10^20 @8:57 ? I'd love to learn why it's 23 instead of 20 as I'm writing notes for my Tuesday class. HHHEEEYYUUULLLPP!!!

    • @gretchenfazakerly5210
      @gretchenfazakerly5210 5 років тому +1

      It would be 23 instead of 20 because he is not just counting the zeros in the number; in scientific notation the exponent is the number that tells you how many numbers are after the decimal, in this case 23 since the decimal would be after 6.
