Follow the PEMDAS order of operations

Calculate within parentheses

[6 - 2 - (1 - 8) - 3 + 6] : 14

6 - 2 - (1 - 8) - 3 + 6

Calculate within parentheses

(1 - 8) : - 7

1 - 8

1 - 8 = - 7

= - 7

= 6 - 2 - (- 7) - 3 + 6

Add and subtract (left to right)

6 - 2 - (- 7) - 3 + 6 : 14

6 - 2 - (- 7) - 3 + 6

6 - 2 = 4

= 4 - (- 7) - 3 + 6

Apply rule

- (- a) = + a

- (- 7) = + 7

= 4 + 7 - 3 + 6

4 + 7 = 11

= 11 - 3 + 6

11 - 3 = 8

= 8 + 6

8 + 6 = 14

= 14

= 14

= 5 - 14 + 5

Add and subtract (left to right)

5 - 14 + 5 : - 4

5 - 14 + 5

5 - 14 = - 9

= - 9 + 5

- 9 + 5 = - 4

= - 4

= - 4
