Cool that was it thanks.

Answer 5

Yw

Answer 6

(Z/nZ)* is a multiplicative group and is only part of the picture of Z/nZ which typically represents a *ring* Z/nZ (and for prime n you get finite fields since you no longer have to worry about zero-divisors)

Answer 7

it's basically the ring of integers modulo \(n\) with usual addition, multiplication

Answer 8

the notation is suggestive of the fact that \(n\mathbb{Z}\) is an ideal of \(\mathbb{Z}\) and the ring \(\mathbb{Z}/n\mathbb{Z}\) is a quotient (namely of \(\mathbb{Z}\) mod \(n\mathbb{Z}\))
