= 4

= - 4 - 2 (- 2)

Multiply and divide (left to right)

2 (- 2) : - 4

2 (- 2)

Apply rule

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

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

= - 4

= - 4 - (- 4)

Add and subtract (left to right)

- 4 - (- 4) : 0

- 4 - (- 4)

Apply rule

- (- a) = + a

- (- 4) = + 4

= - 4 + 4

- 4 + 4 = 0

= 0

= 0

- 2^{2} - 6

2 \times 7^{2}

2 + 2^{1} + 2^{2} + 2^{3} + 2^{4} + 2^{5}

- 2 (5) + 2

- 2 (5) + 3
