Quotient ring is a ring homomorphism
https://math.stackexchange.com
Notice that the quotient ring operations are defined as: (a+I)+(b+I)=(a+b)+I and (a+I)⋅(b+I)=(ab)+I.

1 A ring homomorphism is a map φ : R → S satisfying. 1 φ(a + b) = φ(a) + φ(b) for all a, b ∈ R. 2 φ(ab) = φ(a)φ(b) for all a, b ∈ R.
