- (- 8)^{2} - 6 (- 8) + 7

- 9

Solution steps

- (- 8)^{2} - 6 (- 8) + 7

Follow the PEMDAS order of operations

Calculate exponents

(- 8)^{2} : 64

(- 8)^{2}

Apply exponent rule:

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

n

is even

(- 8)^{2} = 8^{2} = 64

= 64

= - 64 - 6 (- 8) + 7

Multiply and divide (left to right)

6 (- 8) : - 48

6 (- 8)

Apply rule

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

6 (- 8) = - 6 \cdot 8 = - 48

= - 48

= - 64 - (- 48) + 7

Add and subtract (left to right)

- 64 - (- 48) + 7 : - 9

- 64 - (- 48) + 7

Apply rule

- (- a) = + a

- (- 48) = + 48

= - 64 + 48 + 7

- 64 + 48 = - 16

= - 16 + 7

- 16 + 7 = - 9

= - 9

= - 9

(6) - (7) + (- 7) - (- 6) - (2)

5 + (42 \div 7) + 18 - (4 \times 2) + 46

\frac{1}{9} \times 15 + 5 \div 3

45 - (- 32) + (- 12) - (- 7)

7 \times 2 - (4 + 4)
