Calculate exponents

(- 8)^{2} : 64

(- 8)^{2}

Apply exponent rule:

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

n

is even

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

= 64

= - 64 + 10 (- 8)

10 (- 8) : - 80

10 (- 8)

Apply rule

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

10 (- 8) = - 10 \cdot 8 = - 80

= - 80

= - 64 - 80

Add and subtract (left to right)

- 64 - 80 : - 144

- 64 - 80

- 64 - 80 = - 144

= - 144
