Modulo

21 and 84 are congruent to each other modulo 9, since both numbers leave the same remainder, 3, when divided by 9.

Thus 21 modulo 9 is 3, because when 21 is divided by 9, the remainder is 3.

21 is congruent to 3 modulo 9.

"A is the same as B modulo C" means A is the same as B except for differences accounted for by C.
