How much do you think you will need to retire comfortably at age 60? Would you believe that you're going to need at least $4,000,000? Assuming you're 18-25 years old (or younger), it's true! Sounds hard to believe, but by the end of this discussion, you should be a believer. The first thing you need to do is define "comforta
Define a relation R on N × N by (a, b)R(c, d) if and only if a + b = c + d. (i) Prove that R is an equivalence relation on N × N. (ii) Let S denote the set of equivalence classes of R. Show that there is a 1-1 and onto function from S to N. I'll attempt the first part a + b = a + b so (a, b)R(a, b) i.e. R is reflexive
