﹝Binary System﹞ has two numbers 0 and 1. The carry rule is "two in one" and "one out of two". The famous German mathematician Leibniz (1646- 17 10) founded binary mathematics. He once predicted that this mathematical operation (1698) is very lengthy. For example, the binary form of 567 is1001kloc-0/01,but it is very important for scientific research. 1946, the first electronic computer came out, and the binary number was used as the basic number of the computer. Since then, people have paid more and more attention to binary numbers. Because the electronic computer is composed of various electronic components, and the electronic components have only two states of "on" and "off", it is easy to express them by binary numbers. But the fatal weakness of using binary numbers is that it takes a long time to write. In order to solve this contradiction, electronic computers have to convert the operations of these number systems and their mutual conversion into the digital basis of electronic computers, so they are also called "computer mathematics". It should be calculated as follows: ~ 1= 1.

2= 10

3= 1 1

4= 100

5= 10 1

6= 1 10

7= 1 1 1

8= 1000

9= 100 1

10= 10 10 and so on!

Binary system is binary system, and 0 and 1 are basic operators. Modern electronic computer technology uses binary, because it only uses 0 and 1, which is very simple and easy to realize electronically. Binary arithmetic rule addition 0+0 = 0, 0+ 1 = 1+0 = 1,10 subtraction 0-0 = 0,1-0 = 0 ×/.
