    Thanks. 1 is not always used. For 17 this creates a multiplier of 3. See the links given in the annotations for more.

    Thanks for the comment. For 42016 divided by 19 - the remainder you don't divide the 2, you just leave it, so we have a remainder 7...
    We can can prove this as 2211 x 19 = 42009 - where we need 7 more to make 42016.

    Helping my son figure out a way to get his early morning work done in time. His teacher assigns this as bell work first thing in the morning, and it's bringing his grade down. Trying to show him there's way to beat an unfair system. Thanks for the video.

      @FlyingMonkies325 Maybe you should've double checked there... The answer is 2211 remainder 7, not 2100 remainder 16. Where did you even get that from?

    • @novamc7945
      @novamc7945 2 роки тому

      You can confirm this using a calculator. 42016 / 19 = 2211.(something here). Using modulo function with parameters as 42016 and 19, we get 7. So the answer is 2211 + 7/19. Not 2100 + 16/19.

    Dividing 1374 by 19 also take ridiculous amount of time when you have to first find out how many times 19 goes into 137 and then do that muliplication while tecmath is already on the second digit if not farther. Thanks for the technique. I understand it speeds up with practice. Saves a lot of space and keeps you working with single or double digits at most.

  • @jimmyfortef3674

    The remainder is incorrect according to the calculator. It should either be r8 or r35 depending what number it's divided by

    • @ameenpanthakkan
      @ameenpanthakkan Рік тому

      at last the remainder is 22 which is larger than 19 so we can substract with 19 (which means 19 ×[1] =19, the number in square bracket is added). and we get 3.
      do you understand😊

  • @MissCharliechop
    @MissCharliechop 5 років тому +2

    once you get it, it is faster than long division. If you're looking for a "easy" aka lazy method i haven't found it. took me a bit to remember steps but it is faster for solving division when doing a timed test

    • @NoOne-qi4tb
      @NoOne-qi4tb 2 роки тому

      It isn't faster when it takes me 10 seconds to solve it, then i come out and next week i see a lower score because i did the division wrong, it doesn't seem to work for me on most numbers.

      @HellisListening1 8 років тому +1

      +Zee Ox This isn't the basics. Most people can't divide 5 digit numbers with 2 digit numbers(in there head). For everyone watching this video. IT IS FOR SUPER NERDS!!!! YOU CAN GRADUATE HIGH SCHOOL AND USE A CALCULATOR THE WHOLE TIME. And at the rate tech is advancing you will always have one with you(maybe even an AI). That being said if you look to the right side of the comments there is long division trick 4 easily and quickly. This is trick 1 so the latter is probably easier to understand...

  • @ivanhenricksinder

  • @putraadhiguna2934
    @putraadhiguna2934 6 років тому +1

    The method is helpful for those who dont like to (or slow to - like me) guessing the multiplies of the divisor and going trial-and-error, with this method it will instead run through step by step like clockwork

  • @capricornmommy4
    @capricornmommy4 11 років тому +2

    I have the same question as Bert. The only part I didn't get was at the very end, after you subtracted the original 19 from the r22 (I get that), then you crossed out the 8 and made it a 9. Is the one you added to the 8 actually the multiplier (1)? If so, then do you only add the multiplier in this manner to the last number (before the remainder) IF remainder is larger than the original divisor (that was subtracted from remainder)? Make sense? :-)

    what do we do when we encounter a situation where the multiplier is negative and larger than the "other" number for instance 36718/63 here
    my calculations are:
    divide 6 with a multiplier of -3
    3/6= 0 - 3 remaining
    30+6=36/6 = 6 - 0 remaining
    7+(-3*6) = -11/6 =???
