12

Solution steps

- 3^{2} - 9 (- 3) - 6

Follow the PEMDAS order of operations

Calculate exponents

3^{2} : 9

3^{2}

3^{2} = 9

= 9

= - 9 - 9 (- 3) - 6

Multiply and divide (left to right)

9 (- 3) : - 27

9 (- 3)

Apply rule

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

9 (- 3) = - 9 \cdot 3 = - 27

= - 27

= - 9 - (- 27) - 6

Add and subtract (left to right)

- 9 - (- 27) - 6 : 12

- 9 - (- 27) - 6

Apply rule

- (- a) = + a

- (- 27) = + 27

= - 9 + 27 - 6

- 9 + 27 = 18

= 18 - 6

18 - 6 = 12

= 12

= 12

- 5^{2} + 2 \div 2

13 - 8 + (- 3) - (- 16) - 4

(720 + 3728) \div 9 - 68 - 15 \div 5 \div 3

- 1 \times 3 + 4 - 2 \times (- 5) + 10 - 8

- 2 (- 2) - 2
