![]() ![]() This congruence relation is typically denoted a ≡ b (mod n).Ī familiar example of modular arithmetic is the 12-hour clock where numbers "wrap around" upon reaching the modulus (12). In modular arithmetic, for a positive integer n, two numbers a and b are said to be congruent modulo n, if their difference a − b is an integer multiple of n (that is, there is an integer k such that a − b = nk). 1: Decimal multiplication table for the integers between 0–9 In the States, many educators teach elementary decimal multiplication with times tables up to 9 × 9.įig. In mathematics, a multiplication table or times table defines a multipli-cation operation for an algebraic system.
