5

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 = - 5

= - 5 + (- 20) + (30)

Apply rule

+ (- a) = - a

+ (- 20) = - 20

= - 5 - 20 + (30)

- 5 - 20 = - 25

= - 25 + (30)

- 25 + (30) = 5

= 5

(6)^{2} + (8)^{2}

2 \div 3 \div 10

(- 10) - 25 - (- 2)

4 (2)^{3} - 12 (2)^{2}

(- 2 - 5) (- 2 + 3)
