Please post your code, so that we can see what is going on.

Have you ever studied Boolean Algebra? You could get the bit patterns for two numbers and add them the hard way, just like the CPU does. See if this makes any sense at all: http://thalia.spec.gmu.edu/~pparis/classes/notes_101/node109.html

Frankly, this sounds like a ton of fun to implement ... make HalfAdder and FullAdder objects, chain them together. Extremely geeky.
