Before we begin, we introduce the 3 theorems:1. Multiplication inverse (also called the reciprocal in Wikipedia, of course, after mod p, is actually the countdown is not it?) ）:If Ax≡1 (mod p), and GCD (a,p) =1 (A and P coprime), then a

 In a computer system, all values are represented (stored) by supplementary codes ). The main reason is that the complement code can be used to process the symbol bit and other digits in a unified manner. At the same time, the subtraction can also

1. Why do we prefer hexadecimal? The hexadecimal number is 16, 1, and 2, and 1. 2 ^ 4 = 16. Hexadecimal to one digit corresponds to binary to four digits (hexadecimal 10 = binary 1 0000, hexadecimal 100 = binary 1 0000 ). Therefore, the hexadecimal
