A number in base 2 (binary) is a number such that each of its digits is 0 or 1. To convert from binary to decimal (base 10), the digits starting from the right are multiplied by powers of 2 (starting at 0) and added. For example, the value in decimal of 10011 is calculated as follows: 1 ×2 0+ 1 ×2 1+ 0 ×2 2+ 0 ×2
