(- 2) - (- 3) - (- 20) - (30)

- 9

Solution steps

(- 2) - (- 3) - (- 20) - (30)

Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

- (- a) = + a

- (- 3) = + 3

= (- 2) + 3 - (- 20) - (30)

(- 2) + 3 = 1

= 1 - (- 20) - (30)

Apply rule

- (- a) = + a

- (- 20) = + 20

= 1 + 20 - (30)

1 + 20 = 21

= 21 - (30)

21 - (30) = - 9

= - 9

2^{5} \div 2

\frac{1}{2} (- 9)^{2} + 6 (- 9) + 20

8 \div 4 \times 5 + 3 - 8 \div 2 \times 4

3 (7 - 2 \times 3)

4 + (9 \cdot 2) \div (4 - 1) - 4
