(- 3)^{2} : 9

(- 3)^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 3)^{2} = 3^{2} = 9

= 9

= 9 + 8 (- 3) + 15

Multiply and divide (left to right)

8 (- 3) : - 24

8 (- 3)

Apply rule

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

8 (- 3) = - 8 \cdot 3 = - 24

= - 24

= 9 - 24 + 15

Add and subtract (left to right)

9 - 24 + 15 : 0

9 - 24 + 15

9 - 24 = - 15

= - 15 + 15

- 15 + 15 = 0

= 0

= 0

- 5^{2} + 2

- 5^{2} - 1

15 + (- 6) \times (- 9)

- {- 4 - (- 6) + [(- 3) + 4 - 5] + 6}

6 - 8 + 5 \times 2
