Multiply and divide (left to right)

2 (1) : 2

2 (1)

Apply rule:

(a) = a

(1) = 1

= 2 \cdot 1

Multiply the numbers:

= 2

= 1 - 2 - 3

Add and subtract (left to right)

1 - 2 - 3 : - 4

1 - 2 - 3

1 - 2 = - 1

= - 1 - 3

- 1 - 3 = - 4

= - 4

= - 4

(- 3)^{2} + 5 (- 3) + 9

2 \times 2^{2} + 5 \times 3 + 9

2^{31} - 1

- 2^{2} + 3^{2}

3 (- 2) - 5
