Z Modulo 5

Z Modulo 5. To find 1 mod 5 using the modulus method, we first find the highest multiple of the divisor (5) that is equal to or less than the dividend (1). The answer to the first question is clearly no, since you must have th.

For example, 1 + 2 ≡ 3 (mod 6) corresponds to z 1 · z 2 = z 3, and 2 + 5 ≡ 1 (mod 6) corresponds to z 2 · z 5 = z 7 = z 1, and so on. In z 5, each of 1, 2, 3, and 4 is relatively prime to 5, so none can be zero divisors and all can be cancelled. The last set is the set of remainders coprime to the modulus n.
