# 3.  (i) For any integer a, what is (–1) × a equal to?      (ii) Determine the integer whose product with (–1) is          (a) –22        (b) 37        (c) 0

(i) For any integer a, $(-1) \times a = -a$ , i.e, the additive inverse of the given integer.
(ii) The integer whose product with $(-1)$ gives the following are:
$\\ (a)\ -22 : 22 \\ (b)\ 37 : -37 \\ (c)\ 0 : 0$
