Follow the PEMDAS order of operations

Calculate exponents

(- 4)^{2} : 16

(- 4)^{2}

Apply exponent rule:

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

n

is even

(- 4)^{2} = 4^{2} = 16

= 16

= - 16 + 6 (- 4) - 9

Multiply and divide (left to right)

6 (- 4) : - 24

6 (- 4)

Apply rule

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

6 (- 4) = - 6 \cdot 4 = - 24

= - 24

= - 16 - 24 - 9

Add and subtract (left to right)

- 16 - 24 - 9 : - 49

- 16 - 24 - 9

- 16 - 24 = - 40

= - 40 - 9

- 40 - 9 = - 49

= - 49

= - 49

(- 13) + 32 - 8 - 1

(2)^{3} + 9 \times (2)^{2} - 34 \times (2) + 24

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

3 (- 2)^{2} + 12 (- 2) + 9

3 \cdot 24 - 5 \cdot 4^{2} - 217 \div 7
