Mathematics(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 $a$ , what is $(- 1) \times a$ equal to?
(ii) Determine the integer whose product with $(- 1)$ is
(a) $- 22$
(b) 37
(c) 0

(i) Consider the given expression $(- 1) \times a$ .

Perform multiplication to get the following,

$(- 1) \times a = - a$ .

Hence, any integer $a$ is multiplied with $(- 1)$ which produces the additive inverse of integer $a$ .
