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

- 63

Solution steps

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

Follow the PEMDAS order of operations

Calculate exponents

(- 3)^{2} : 9

(- 3)^{2}

Apply exponent rule:

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

n

is even

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

= 9

= - 6 \cdot 9 + 2 (- 3) - 3

Multiply and divide (left to right)

- 6 \cdot 9 : - 54

- 6 \cdot 9

- 6 \cdot 9 = - 54

= - 54

= - 54 + 2 (- 3) - 3

Multiply and divide (left to right)

2 (- 3) : - 6

2 (- 3)

Apply rule

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

2 (- 3) = - 2 \cdot 3 = - 6

= - 6

= - 54 - 6 - 3

Add and subtract (left to right)

- 54 - 6 - 3 : - 63

- 54 - 6 - 3

- 54 - 6 = - 60

= - 60 - 3

- 60 - 3 = - 63

= - 63

= - 63
