1. Residual: The remainder after the division is divided, for example:
MOD 4 = 2; -17 MOD 4 =-1; -3 MOD 4 =-3; 4 MOD (-3) = 1; -4 MOD 3 =-1;
If a mod B is an XOR, then the resulting symbol is the same as a; Of course, a mod B is equivalent
The beauty of the original root G of the modulo prime p is reflected in the presence of a non-zero number G power of each modulo p. Therefore, for any number 1
G, G ^ 2, G ^ 2, ''', G ^ (P-2), G ^ (pm)
Exactly the same as model a P. The

Method 1:
Everyone can think of it. Calculate the value of a * B and then calculate the value of a * B mod C. This is

Order of integers: set A and n are positive integers of the a^x=1, making the smallest positive integer x (mod n) The order of a modulo n//order Template: A^x=1 (mod M), call Getjie (a,m)//Input: 10^10>a,m>1//output: No solution returned-1, with a

Yesterday, when learning the mathematical functions of MATLAB, the tutorial mentions that modulo (MoD) and take-rest (REM) is different, today on the Web specifically checked:
Usually the modulo operation is called the rest operation, and they
