Solution steps

4 - (2) (4)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

(2) (4) : 8

(2) (4)

(2) (4) = 2 \cdot 4

(2) (4)

Apply rule:

(a) = a

(2) = 2

= 2 (4)

Apply rule:

(a) = a

(4) = 4

= 2 \cdot 4

= 2 \cdot 4

Multiply the numbers:

2 \cdot 4 = 8

= 8

= 4 - 8

Add and subtract (left to right)

4 - 8 : - 4

4 - 8

4 - 8 = - 4

= - 4

= - 4

(- 1)^{3} - 4 (- 1)^{2}

2 \times 0 - 1

(- 6 + 5)^{2}

- 5 + 5 (8 + 12)

- 3^{2} - 5 \times (- 2) + 8^{2} - 7
