Question

9. Evaluate each of the following:
(i) 13 = [(-2) + 1]
(ii) [(-36) = 12] = 3
(iii) 0 = (-12)
(iv) [(-6) + 5)] = [(-2) +1)​

Answer 1

Answer:

(i)     13 = [(-2)+1]

       13 = -1                        because,  If the two numbers have different sign like positive and negative then subtract the two numbers and give the sign of the bigger number.

(ii)    [(-3+6)-12] = 3

 -48 = 3

(iii)    0 = (-12)

0= -12

(iv)    [(-6) + 5)] =[(-2) +1]

           - 1 = -1
