To submit Let R[r] be the set of all expressions a = do +ajx+ax +.= i=0 where a¡ E R for all nonnegative integers i. Informally, an element of Rx] is like a polynomial except that it can have infinitely many terms. (a) Carefully write down definitions of addition and multiplication operations for R[r], analogous to the definitions for R[x] in the notes. Given a,b e R[x], your defi- nitions should indicate what each coefficient of the sum a +b and product ab is.
