For any integers x and y, sum (x, y) and diff (x, y) denote the sum and the difference of x and y, respectively. For example, sum (1, 2) = 3 and diff (1, 2) = -1. For the integer p, what is the value of sum (10, p)?

(1) diff (diff (10, p), sum (10, p)) = sum (diff (10, p), sum(10,p))
(2) sum(10, p) = diff (-10, p)
