Binary Addition Rules
The binary addition rules are:
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 0 (and carry 1)
1 + 1 + 1 = 1 (and carry out).
These are demonstrated below:




Binary Addition – Example 1
The two numbers being added together are written on top of each other in the same way that long addition is performed with binary addition.
We then work from right to left applying the riles

Binary Addition – Example 2

Binary Addition – Example 3

Remember the Rules
