Adding Binary is like the simple bus stop method, except you can only work with 1's and 0's, and as it is Binary, you cannot go over number 1, so if it is a 00, it is still 0, if it is 01, it is 1 as 0 plus 1 is 1, if it is 11 it is 0 and you carry the 1, as you cannot go over 1. And remember, the answer will be in Binary, so work out your answer using Denary.
So for example, 1010
1110
=10000, which in Decimal is 16.
A quiz if you want to give it a shot.
