I Modulo N

I Modulo N. Modulo n is usually written mod n. In modular arithmetic, x ≡ 1 means that x and 1 belong to the same residue class.

Modulo a prime number we have seen that modular arithmetic can both be easier than normal arithmetic (in how powers behave), and more difficult (in that we can't always divide). Modulus congruence means that both numbers, 11 and 16 for example, have the same remainder after the same modular (mod 5 for example). Due to ongoing organism additions, this information may be out of date.

Congruence modulo \(n\) prove that congruence modulo \(n\) is a congruence relation on the set of integer with respect to addition and multiplication.

Then finally, we subtract the answer in the second step from the dividend (1) to get the answer. I am using example from gq signature scheme from the book page 451. It remains to show that it is bijective. Program to find remainder without using modulo or % operator.
