Binary Addition

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.

PowerPoint Presentation

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)
