Let R be a ring, let S be a subring of R and let' be an ideal of R. Note that I have proved that (5+1)/1 = {5 +1 | 5 € S) and I defined $:(5+1) ► S(SO ) by the formula: 0/5 + 1)=5+(SNI). In the previous video I showed that was well-defined. Now show that is a ring homomorphism. In other words, show that preserves both ring addition and ring multiplication. Then turn your work into this...

In the previous video, I made the assumptions that Ris a ring, S is a subring of R and I is an ideal of R. It turns out that the hypothesis that I is an ideal is critical. Show that this hypothesis is critical by proving the following statement: Let R be a ring, and let S and I be subrings of R. Show that S + I is NOT necessarily subring of R by showing that multiplication is not...
