Binary number

The binary numeral system is a way to write numbers using only two digits: 0 and 1. These are used in computers as a series of "off" and "on" switches. In binary, each digit's place value is double than that of the next digit to the right; the place value of the rightmost digit being 1. Example-10110011

     1 = 1
     1 = 2
     0 = 4
     0 = 8
     1 = 16
     1 = 32
     0 = 64
     1 = 128

Here is a list of some numbers that can be made from these digits (zero is represented by a single "0"):

Binary is a numbering system that is a series of 1s and 0s meaning (to the computers) on and off. It is base 2 and our number system (decimal) is base 10. Binary was invented by many people but is credited to Gottfried Leibniz, a German mathematician. The idea of binary was created in the 1600s. Binary has been used in nearly everything electronic; from calculators to supercomputers. Machine code are binary digits.
