comment Ideals of quotient algebras.
I know that I can do this to prove the fact that I've stated. by using kernal and image of the homomorphism. That's not what I was asking though.

comment Solving complex linear congruences
But to answer the question. I don't get why you want to multiply 3+3i by 1-i and why knowing that 5 =-1 and having 5 as a denominator helps us. EDIT: trying to figure out what's 10 mod 3+3i. Lol I'm going full potatoe on this one.

comment Solving complex linear congruences
Yes I get the rationalizing part. I think I rushed a little with asking this question. To be honest I don't even quite get how to find a modulus of a number when working with complex numbers. Like how do you find 5 mod 3+3i? I'm going to play around with these, and I think that should make things a little clearer for me :)

Thanks. This is so simple, can't believe I was struggling with this.
