- 3 (5) (30) : - 450

- 3 (5) (30)

- 3 (5) = - 15

- 3 (5)

Apply rule:

(a) = a

(5) = 5

= - 3 \cdot 5

Multiply the numbers:

- 3 \cdot 5 = - 15

= - 15

= - 15 (30)

- 15 (30) = - 450

- 15 (30)

Apply rule:

(a) = a

(30) = 30

= - 15 \cdot 30

Multiply the numbers:

- 15 \cdot 30 = - 450

= - 450

= - 450

= - 450 + (56) (- 40)

Multiply and divide (left to right)

(56) (- 40) : - 2240

(56) (- 40)

Apply rule

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

(56) (- 40) = - 56 \cdot 40 = - 2240

= - 2240

= - 450 - 2240

Add and subtract (left to right)

- 450 - 2240 : - 2690

- 450 - 2240

- 450 - 2240 = - 2690

= - 2690

= - 2690
