Ib tag nrho cov seem seem modulo m yog ib pawg ntawm cov lej xws li tias txhua tus lej yog congruent modulo m rau raws nraim ib tus lej ntawm pawg. Qhov yooj yim ua tiav qhov seem seem modulo m yog cov lej 0, 1, 2, …, m−1. Txhua integer yog congruent rau ib qho ntawm cov integers modulo m.
Yuav ua li cas hauv qab no yog ua tiav qhov seem seem modulo 11?
1. {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10} yog qhov ua tiav qhov seem seem modulo 11. Txij li 1 ≡ 12 (mod 11), 3 ≡ 14 (mod 11), …, 9 ≡ 20 (mod 11), tag nrho cov seem seem uas muaj tag nrho cov lej yog {0, 12, 2, 14, 4, 16, 6, 18, 8, 20, 10 }.
