Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

+ (- a) = - a

+ (- 18) = - 18

= (2) - 18 + (3) + (- 7)

(2) - 18 = - 16

= - 16 + (3) + (- 7)

- 16 + (3) = - 13

= - 13 + (- 7)

= - 13 - 7

- 13 - 7 = - 20

= - 20

(60 - \frac{1}{8}) \div (30 - \frac{1}{16})

- 5 + 4 - 2 + 8

(1)^{2} - 2 (1)
