(2) we saw that formed a ring with respect to the addition and multiplication which we defined on it. Is the z mod n a subset of z? The purpose of these notes is to show taht (z/nz)∗ is a group under multiplication.

(2) we saw that formed a ring with respect to the addition and multiplication which we defined on it.

The modern approach to modular arithmetic was developed by carl friedrich gauss in his book disquisitiones arithmeticae, published in 1801. When do we do arithmetic modulo some number n? Elements of z/nz, we defined a·b = ab. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers wrap around when reaching a certain value, called the modulus.

For example, to compute 16 ⋅ 30 (mod 11), we can just as well compute 5 ⋅ 8 (mod 11), since 16 ≡ 5 and 30 ≡ 8.

Z mod n 3.2 zn 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.
