Answer 1

Answer:

number line among negative integers, 0 and positive integers.

   

    So, case 1: When a is any negative integer, that is, -a,

    then (−1) × (-a) = a

    So, case 2: When a is 0,

    then (−1) × 0 = 0

    So, case 3: When a is any positive integer, that is, a,

    then (−1) × a = -a

    Thus, the possible answers are a, 0 and -a.

(ii) (a) 

(b) −37×(−1)=37-37×-1=37
