Proof: Suppose a ? b mod n. Then by Theorem 3.3 b = a + nq. If a leaves the remainder r when divided by n
Congruences
If n is an integer then a is congruent to b modulo n if and only if a and b have the same remainder when divided by n. Proof. By the division algorithm

What is the remainder when n is divided by 4?
- When an integer (n) is divided by 4 the remainder is 2, when the same integer is divided by 3, the remainder is 1. What could be the value of n?
When is a set formed by all remainders?
- 3. A set is formed by all remainders when the odd numbers between 8 and 800 are divided by 5. What is the mode of the set? (A) 0 (D) 3 (B) 1 (E) 4 (C) 2.
Why is a mod b not a remainder?
- It is because a mod b isn't simply the remainder as returned by the operator '%'. See some examples: There are some other definitions in math and other implementations in computer science according to the programming language and the computer hardware. Please see Modulo operation from Wikipedia.
