Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

+ (- a) = - a

+ (- 12) = - 12

= - 23 - 12 - (- 18) - 8 + 7 + 18

- 23 - 12 = - 35

= - 35 - (- 18) - 8 + 7 + 18

Apply rule

- (- a) = + a

- (- 18) = + 18

= - 35 + 18 - 8 + 7 + 18

- 35 + 18 = - 17

= - 17 - 8 + 7 + 18

- 17 - 8 = - 25

= - 25 + 7 + 18

3 \cdot 16 + (1 - 5)^{3}

- 25 + (- 32) + (- 44)

(12)^{2} - 4 (1) (- 8)

4 + 4 \div 4

- 3 (- 4) - 17
