Solution steps

6 (4) - 9 (4) (- 5)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

6 (4) : 24

6 (4)

Apply rule:

(a) = a

(4) = 4

= 6 \cdot 4

Multiply the numbers:

6 \cdot 4 = 24

= 24

= 24 - 9 (4) (- 5)

Multiply and divide (left to right)

9 (4) (- 5) : - 180

9 (4) (- 5)

9 (4) = 36

9 (4)

Apply rule:

(a) = a

(4) = 4

= 9 \cdot 4

Multiply the numbers:

9 \cdot 4 = 36

= 36

= 36 (- 5)

Apply rule

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

36 (- 5) = - 36 \cdot 5 = - 180

= - 180

= 24 - (- 180)

Add and subtract (left to right)

24 - (- 180) : 204

24 - (- 180)

Apply rule

- (- a) = + a

- (- 180) = + 180

= 24 + 180

24 + 180 = 204

= 204

= 204
