Binary is a digital system widely used in computing technology. Binary numbers are numbers represented by 0 and 1. Its cardinal number is 2, the carry rule is "every two enters one", and the borrowing rule is "borrowing one as two", which was discovered by the German master of mathematical philosophy Leibniz in18th century. The current computer system basically uses a binary system. ?

The invention and application of the computer, known as one of the important symbols of the third scientific and technological revolution in the 20th century, has a binary operation mode, which proves that the Leibniz principle is correct.

The characteristics of binary system:

If the value of the 0th bit of a binary number (integer) is 1, then this number is odd; If this bit is 0, then this number is even.

If the low-order n bits of a binary number are all zeros, then this number can be divisible by 2n.

If the nth bit of a binary number is 1 and all other bits are 0, then this number is equal to.

The result of shifting all the bits of a binary number to the left is to multiply the number by two.
