Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

+ (- a) = - a

+ (- 11) = - 11

= (- 12) - 11 - (10) - (- 3)

(- 12) - 11 = - 23

= - 23 - (10) - (- 3)

- 23 - (10) = - 33

= - 33 - (- 3)

= - 33 + 3

- 33 + 3 = - 30

7 - 2 \times 3 + 1 \times (- 4)

63 \div 7 + (12 - 8) \times (5 \times 2) - 18 + 4

- (1 - 2)^{2} + 3

2 (4)^{2} + 4

2 + 2 \times 5
