    There are 10 types of people in the world:
    Those who thought that this joke is in binary
    Those who thought that this joke was in trinary
    Those who thought this joke is in quatenary
    Those who think that this joke is in quintenary
    Those who think this joke is in sektenary
    Those who think this joke is in septenary
    Those who think that this joke is in octanary
    Those who bored and think that this is a nonnary joke
    Those who think that this is a base 10 joke
    And people that continue reading after getting the right answer

      HelloItsMe every system is base "10" but since that would get confusing we always make the number after the "base" be in out base 10. It's arbitrary but it gets the point across.

    I love math and I am pretty good at mental arithmetic so it really surprised me how hard it was to do binary subtraction. Not to mention how hard it is for my computer class to do it. I finally figured it out how to solve my problem by instead of borrowing from the one making 0 than the 0 make 10 than 10 make 1 etc etc etc borrow from 100 or 1000 or 10000 all you have to do is flip all the the numbers. It Works. :) And is faster and less complicated.

    I, at first, converted the numbers from base 2 to base 10. Then I do the operations, plus or minus. Then I converted the results from base 10 to base 2. But the method you have learnt is awesome!

    You would have made a great computer scientist. In the 1960s programmers had to program in binary. The 1970s had octal. Now we use hexidecimal. I think we should have dedicated digits for eleven through fifteen instead of letters.great video!

      Works the same. Do it out the long way:

      ___x1100
      ________0
      _______0_
      __10011__
      _10011___
      __1001100
      +10011000
      =11100100
      In decimal:
      19*12=228 Which is correct.

    I want to pose a question here. Why do we call the base represented in this video base 2? I understand that base 2 refers to two digits and makes conversion easy between base 10 and base 2, but imagine some alien species only has two total fingers. They would call their base containing the digits 1 and 0 as base 10, while calling the human’s most common base as base 1010. There would then be two bases called base 10 if looking at both perspectives, one with digits from 0-1 and the other with digits 0-9.

  • @沈博智-x5y
    @沈博智-x5y 4 роки тому

    I think I prefer to solve subtraction a different way.
    101 - 11 = 101 - 011
    change 011 ~ 100 (change 1 -> 0 and 0-> 1)
    therefore now let's solve 101+100=1001
    get rid of the first digit because we are subtracting not adding 1001 > 101
    so change 1001 ~ 001 (digit in first position removed)
    now all we have to do is add 1 now.
    001 + 1 = 10
    therefore 101-11 = 10
    ---------------
    11001 -1110 = 11001 - 01110
    change 01110 ~ 10001
    therefore 11001 + 10001 = 101010
    get rid of first digit
    change 101010 ~ 01010
    add 1: 01010 + 1 = 1011
    therefore 11001 - 1110 = 1011
    ------
    the algorithm is if we have a - b where a and b are binary numbers, add extra 0s at the start of b if necessary to make it the "same size" as binary number a, then change all the 0s in binary number b into 1s and all the 1s in binary number b to 0s.
    then compute a+b but get rid of the first digit.
    after getting rid of the first digit, we need to compensate the 1 we lost for swapping 1s and 0s by adding 1 afterwards.
