Question

Calcule a) (-2)3-(-1)2+(-3)2-(-2)3

Answer 1

Resposta:

$( - 2) \times 3 = - 6$

$- 6 - ( - 1) \times 2 - 3 \times 2 - ( - 6)$

$( - 1) \times 2 = - 2$

$- 6 - ( - 2) - 3 \times 2 - ( - 6)$

$3 \times 2 = 6$

$- 6 - ( - 2) - 6 - ( - 6)$

$- 6 + 2 - 6 + 6$

$- 6 + 2 = - 4$

$- 4 - 6 + 6$

$- 4 - 6 = - 10$

$- 10 + 6$

$\red{ - 4}$
