Adding in binary is just like adding in denary, only this time, we need to 'carry' a digit if the sum exceeds one.
Before adding, though, we need to make sure that the two unsigned integers are represented by the same number of bits. To do this, we simply add enough zeros to the end of the smaller number so that the numbers of digits match. For example, before computing 1011 1100 + 1100, we should change 1100 to 0000 1100.
On this page, type in two eight-bit unsigned binary integers. The compuer will add them for you and show you how. (Note: You may get an error. We will explain this error in a bit...)
