Answer:

21

Explanation:

Let's start solving the equation step by step:

-7 (-8 - (-6) + 8 ÷ (-2)³)

So, let's start with solving 2³

2³ = 2 × 2 × 2 = 8

So, the equation will be:

-7 (-8 - (-6) + 8 ÷ -8)

= -7 (-8 + 6 + (-1)) [1. I have divided 8 and 8 to get -1]

[2. I have performed (-ve × -ve = +ve) to get +6]

= -7 (-8 + 6 - 1) [I have performed (-ve × +ve = -ve) to get -1]

= -7 (-3) [I have added -8 and 6 and (-1)]

= -7 × -3 = 21 [-ve × -ve = +ve]

Thus, the answer is 21

If I am wrong, please do correct me :)
