e.

[ -[12 - ( - 3)] - 15]×(5 - 12)

[ -[12 + 3] - 15]×(5 - 12)

[ -[15] - 15]×(5 - 12)

[ -30]×(5 - 12)

[ -30]×(-7)

210

f.

[24 + (3 - 8 - 4)] ÷ (4 - 9)

[24 + (-5 - 4)] ÷ (4 - 9)

[24 + (-9)] ÷ (4 - 9)

[15] ÷ (4 - 9)

[15] ÷ (-5)

-3

g.

[(-8 + 6 - 3)× (-4)] ÷ ( - 12 + 8)

[(-2 - 3)× (-4)] ÷ ( - 12 + 8)

[20] ÷ ( - 12 + 8)

[20] ÷ ( - 4)

-5

h.

-29 + (5 - [15 + 7× (3 - 6) + ( -3 - 5)])

-29 + (5 - [15 + 7× (-3) + ( -8)])

-29 + (5 - [15 + (-21) + ( -8)])

-29 + (5 - [-6 + ( -8)])

-29 + (5 - [-14])

-29 + (5 +14)

-29 + (19)

-10

i.

[[( -30 ÷ 3) + 8] × ( - 12)} ÷ [- (5 + 9 - 10)]

[[( -10) + 8] × ( - 12)} ÷ [- (14 - 10)]

[[-2] × ( - 12)} ÷ [- (14 - 10)]

[[-2] × ( - 12)} ÷ [- (4)]

[24} ÷ [- 4]
