Answer 1

a. (3 - 8) + [5 - (-2)]

= - 5 + [5 + 2]

= - 5 + 5 + 2

= 2

b. 5 - [63 - 2 - (12 - 8) - 3 + 6]

= 5 - [63 - 2 - 4 - 3 + 6]

= 5 - 60

= - 55

c. 18 ÷ [12 ÷ (-2)]

= 18 ÷ (- 6)

= - 3

d. (5 + 3 . 2 ÷ 6 - 4) . (4 ÷ 2 - 3 + 6)

= (5 + 6 ÷ 6 - 4) . (2 - 3 + 6)

= (5 + 1 - 4) . ( 5 )

= ( 2 ) . ( 5 )

= 10

e. (7 - 2 + 4) - (2 - 5)

= ( 9 ) - ( -3 )

= 9 + 3

= 12
