How do you count in binary?

Counting in binary involves using only two digits, 0 and 1. To count in binary, you start with 0, then 1, and then continue by adding a digit each time you reach the highest value. For example, after 1 comes 10, then 11, and so on. Each digit's place represents a power of 2, with the rightmost digit being 20, the next being 21, and so on.
