    It’s in the math forum, so you must be serious.

    405 equals…

    4 hundreds
    0 tens
    5 single units

    Re: how subtrat numbers(minus)?

    after read the Arnoutdv and seen a video about subtraction, i learned...
    1 - how can i subtract the low number with big number: 45 -312?
    here we change the signal and the result must be negative:
    45 - 312 => 312-45 =267... but the signal was minus... so the result is -267


    2 - how can i subtract a number with several zeros?
    sample 1: 3000 - 234
    the 3000 is 'converted' to 299'10':
    299 10
    - 23 4
    --------------
    276 6
    3000-234 = 2766


    sample 2: 3004 - 237
    here it's the same:
    3004 must be 'converted' to 299'14':
    299 14
    - 23 7
    --------------
    276 7
    3004-237 = 2767
    thank you so much for all to all

    I don't see the problem. I'd always recommend the Decimal datatype if you need precision and accuracy
