Follow the PEMDAS order of operations

Multiply and divide (left to right)

9 (0) : 0

9 (0)

Apply rule:

(a) = a

(0) = 0

= 9 \cdot 0

Apply rule:

a \cdot 0 = 0

= 0

= 0 - 2 (- 4)

Multiply and divide (left to right)

2 (- 4) : - 8

2 (- 4)

Apply rule

a \cdot (- b) = - a \cdot b

2 (- 4) = - 2 \cdot 4 = - 8

= - 8

= 0 - (- 8)

Add and subtract (left to right)

0 - (- 8) : 8

0 - (- 8)

Apply rule

- (- a) = + a

- (- 8) = + 8

= 0 + 8

0 + 8 = 8

= 8

= 8

(- 3) + (- 5) - (- 9)

5^{5} - 4^{5}

- 3 - (3 + 5 \cdot 3) - 1 \cdot 4

10800 - 850 (10)

- 3 \times (6 + 4 \times 2)
