Computers use binary to process data. There are simple techniques to convert between binary and denary and to add two binary numbers together.

When two numbers are added together in denary, we take the first number, add the second number to it and get an answer. For example, **1 + 2 = 3**.

When we add two binary numbers together the process is different.

There are four rules that need to be followed when adding two binary numbers. These are:

- 0 + 0 = 0
- 1 + 0 = 1
- 1 + 1 = 10 (binary for 2)
- 1 + 1 + 1 = 11 (binary for 3)

Let’s try adding together two binary numbers: 0101 0011 and 0111 0110.

To get to the answer, use the following method:
