Question

3. (i) For any integer a, what is (-1) xa equal to?
(ii) Determine the integer whose product with (-1) is
(a) -22
(b) 37​

Answer 1

Answer:

(a) 22  (b) -37

Explanation:

First sum (a) :-

• If a number (a) is multiplied by a negative number (here, -1) to get a negative number, then the negative number (-1) should be multiplied by a positive number.

• (i.e); (-1) x (a) = -22

                       (-a) = -22

  Therefore    (a)  = 22

Second sum (b) :-

• If a number (a) is multiplied by a negative number (here, -1) to get a positive number , then the negative number (-1) should be multiplied by a negative number.

• (i.e); (-1) x (a) = 37

                        (-a) = 37

    Therefore    (a) = -37
