Follow the PEMDAS order of operations

Add and subtract (left to right)

(8) - (6) = 2

= 2 + (- 7) - (- 4)

Apply rule

+ (- a) = - a

+ (- 7) = - 7

= 2 - 7 - (- 4)

2 - 7 = - 5

= - 5 - (- 4)

Apply rule

- (- a) = + a

- (- 4) = + 4

= - 5 + 4

- 5 + 4 = - 1

= - 1

\frac{2 ^{2} - 16}{2 - 4}

- 4 - 3 \times (- 2)

(\frac{1}{2} \div 2) \div 4

1 - (- 3 + 6 + 1) - [4 - (6 - 3 + 1) - 2]

(- 2)^{2} + 7
