Question

6. Evaluate each of the following:
(iii) |-9| +|-6|
(i) |- 17|-|8|
(ii) |-14| + |5|
(iv) |–23|-|-12|
(v) |-81+1-6|-|-10| (vi) |-6|+|-1|-|-5|​

Answer 1

(iii)

$- 9 + ( - 6) = - 9 - 6 = - 15$

(ii)

$- 14 + 5 = - 9$

(i)

$- 17 - 8 = - 25$

(iv)

$- 23 - ( - 12) = - 23 + 12 = - 11$

(v)

$- 81 + 1 - 6 - ( - 10) = - 76$

(vi)

$- 6 - 1 + 5 = - 7 + 5 = - 2$
