ok I read some ones quote that 1+1=10, I know this is binary but I cant figure it out, I would have thought 1+1 = 11 but then again im just guessing, thanks for not making fun of me.

    It's quite simple, actually...Since binary is BASE 2, you can't have a number higher than 1, so when you add 1 to the existing value of one, it becomes 2, which in binary is 10, since each digit going left is twice what the one to the right of it is, starting at 1.· For example:

    128 64 32 16 8 4 2 1· <---Here is what the first 8 bits are worth.· A 1 in any of these positions is worth the number shown in that order.· For example 1000 binary is equal to 8 decimal.· 11 binary would be equal to 3 decimal.

    BTW, it wasn't necessary to make a new screen name to ask the question, although I did move it to the appropriate forum.

    binary counts as follows:
    000 = 0
    001 = 1
    010 = 2
    011 = 3
    100 = 4
    101 = 5
    110 = 6
    111 = 7

    and so forth

    LOL @ "BTW, it wasn't necessary to make a new screen name to ask the question, although I did move it to the appropriate forum."

    the misleading thing is that you read it as one plus one equals ten, whereas it actually is one plus one equals 2
    or
    1+1 = %10

    or

    1+1 = 2
    1+1 = %10 (as nick mentioned)
    1+1 = $2
    1+1 = 0x02
    Does octal have any prefix?

    <edit>
    1+1 = o010

    Originaly the letter o as in oscar was used. Because of confusion it was preferable to use the letter "q".

    Nick,

    · In all of my texts from collefe, Hex is preceeded with $, Binary with % and Octal with &.
