    I know how to add easy binary but when you have FOUR 1's in a column of addition... What do you do? Can't seem to find a solution! Help please!
    e.g.
    01101101
    00100111
    00101101

    well you can do A+B+C in one go (with a lot of carry digits to handle)

    or do (A+B) and then add C to the result... which is IMO more manageable and less error prone.

    Just separate the numbers, If you know how to add 2 number you'll be fine.

    01101101+
    00100111 then just add 00101101 to the product.

    Okay, but just out of curiosity, what would you do if you had to add all three together and you had 4 1's in a column?

    Well it would loook like this

    0001
    0001 +
    0001
    0001
    ---------
    0100

    So really just apply that to whatever situation you came across. If you had to extend it by a bit then you would just do so.
