(i) For any integer a, what is `(-1) xx a` equal to?
(ii) Determine the integer whose product with `(-1)` is
(a) `- 22`
(b) `37`
(c) `0`

Text Solution

Verified by Experts

(i) For any integer a,` (-1) ×` a is equal to - a,
So,`( -1 )×` a = `- `a

(ii) `(a) ? × (-1) = -22`
Let, a be the required integer
thus,`a × (-1) = -22 -------- (1)`
`=> -a = -22`
