The '''binary system''' is a way of representing numbers in base 2, i.e. using only the digits 0 and 1. A number written in the system can be denoted by following it with a subscipt 2, i.e. <sub>2</sub>. Each digit represents the number of a power of 2 in the complete number, similarly to in the [[decimal system]], where each digit represents the number of a power of 10. The power is defined by the number of digits in the number from right to left through the digit, minus 1, e.g. 100<sub>2</sub>, where the digit 1 is the third digit from the right, and thus represents 2<sup>2</sup>, or 4. While it is generally impractical for [[human]] use, it is the mainstay of modern [[computing]].
