(2)^{2}

(2)^{2} = 4

= 4

= 4 - 3 (2)

Multiply and divide (left to right)

3 (2) : 6

3 (2)

Apply rule:

(a) = a

(2) = 2

= 3 \cdot 2

Multiply the numbers:

3 \cdot 2 = 6

= 6

= 4 - 6

Add and subtract (left to right)

4 - 6 : - 2

4 - 6

4 - 6 = - 2

= - 2

= - 2

- 6^{2} + 5 (- 6) - 1

- 2 {- [- 3 - 2 (- 5 + 8)]}

- 30 (3) + \frac{11}{2} (49)

4 - 5 \times 5 + 4

5 + (3 + 7) \times 4 - 20 \div 5 - 8
