  • What does a ? b mod n means?

    For a positive integer n, two integers a and b are said to be congruent modulo n (or a is congruent to b modulo n), if a and b have the same remainder when divided by n (or equivalently if a ? b is divisible by n ). It can be expressed as a ? b mod n.

  • What is the mod in algorithm?

    The modulo operation (abbreviated “mod”, or “%” in many programming languages) is the remainder when dividing. For example, “5 mod 3 = 2” which means 2 is the remainder when you divide 5 by 3.

  • What is an example of a B mod N?

    For integers, "a?b (mod n)" means that a-b is a multiple of n. It is often written "a=b (mod n)". For example, 1, 8, 15, 22 are all equal mod 7. This is the basic idea in modular arithmetic, an extremely important idea in mathematics.
  • As with so many concepts we will see, congruence is simple, perhaps familiar to you, yet enormously useful and powerful in the study of number theory. If n is a positive integer, we say the integers a and b are congruent modulo n, and write a?b(modn), if they have the same remainder on division by n.
