4

Solution steps

(- 7) - (- 13) + (- 4) + (2)

Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

- (- a) = + a

- (- 13) = + 13

= (- 7) + 13 + (- 4) + (2)

(- 7) + 13 = 6

= 6 + (- 4) + (2)

Apply rule

+ (- a) = - a

+ (- 4) = - 4

= 6 - 4 + (2)

6 - 4 = 2

= 2 + (2)

2 + (2) = 4

= 4

76 - [- 7 + 5 \times (9 - 14 + 7) - 5] - 4 \times (- 3)

14 + [23 - (34 - 57)]

6 (- 1) - 4

8^{3} - 2 [(3 + 30) \div 3]

(40 - 33)^{2}
