x and y are positive integers such that x + y = 31.  What is the largest possible value of x*y?  What is the smallest possible value of x*y?

Largest = 15 * 16 = 240

Smallest = 0 * 31 = 0

The largest is 15*16 = 240.

Since the question states thta x and y are positive integers, the smallest value is 1*30 = 30
