Binary addition works exactly like decimal. You line up the numbers, and add up each column, starting from the right. However, it is much easier, as the only possible additions are 0+0=0, 0+1=1, 1+0=1, 1+1=10. You do need to carry, but that doesn't complicate things much.

Enter the first and second number in decimal, from 1-63, and click on 'Add' button.
