Calculate exponents

(3)^{2} : 9

(3)^{2}

(3)^{2} = 9

= 9

= 2 \cdot 9 - 5 (3) - 3

Multiply and divide (left to right)

2 \cdot 9 : 18

2 \cdot 9

2 \cdot 9 = 18

= 18

= 18 - 5 (3) - 3

Multiply and divide (left to right)

5 (3) : 15

5 (3)

Apply rule:

(a) = a

(3) = 3

= 5 \cdot 3

Multiply the numbers:

5 \cdot 3 = 15

= 15

= 18 - 15 - 3

= 3 - 3

3 - 3 = 0

= 0

= 0

(- 0)^{2} - 1

- 3 \times 2 - 2

[(- 2) - (4)] \div (- 2) + [(- 32) \div (16)]
