Solution steps

(- 8) - (- 6) - (- 5) - (1)

Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

- (- a) = + a

- (- 6) = + 6

= (- 8) + 6 - (- 5) - (1)

(- 8) + 6 = - 2

= - 2 - (- 5) - (1)

Apply rule

- (- a) = + a

- (- 5) = + 5

= - 2 + 5 - (1)

- 2 + 5 = 3

= 3 - (1)

3 - (1) = 2

= 2

3 \times 5^{2} \div 15 - (5 - 2^{2})

10 + (6 - (9 - 10) + 5)

4 - 7 [- 3 - 2 (10 - (- 2)) - 4 (6 - 7) - 7]

- 2 \cdot 4 + 4

(- 2)^{2} + (- 5)^{2} - (+ 2)^{3} + 4^{2} - 1 0^{2}
