Z Modulo 2Z

Z Modulo 2Z. Show, in general, that the number of gaussian integer equivalence classes, modulo a gaussian integer $z$ is exactly $n(z)$, where $n$ is the norm function. In modular arithmetic, the integers coprime (relatively prime) to n from the set.

The modulo operation, commonly expressed as a % operator, is a useful operation in data coding. To mean n|(b − a). Show, in general, that the number of gaussian integer equivalence classes, modulo a gaussian integer $z$ is exactly $n(z)$, where $n$ is the norm function.

As we shall see, they are also critical in the art of cryptography.

We read this as a is congruent to b modulo (or mod) n. For example, 29 ≡ 8 mod 7, and 60 ≡ 0 mod 15. We use this result to. In modular arithmetic, the integers coprime (relatively prime) to n from the set.

If (z/nz)× is cyclic with generator a + nz, we say that a is a primitive root modulo n.

For instance, the expression 7 mod 5 would evaluate to 2 because 7 divided by 5 leaves a remainder of 2.

We saw in theorem 3.1.3 that when we do arithmetic modulo some number $n$, the answer doesn't depend on which numbers we compute with, only that they are the same modulo $n$.
