$- 1$ $-1$

Given: ${(- 1)}^{3} = (- 1) \times (- 1) \times (- 1)$ $" "(-1)^3" "=" "color(magenta)((-1)xx(-1))color(green)(xx(-1))$

When the signs are the same multiplying gives a plus giving:
$(- 1) \times (- 1) = (+ 1)$ $color(magenta)((-1)xx(-1)=(+1))$

When the signs are different multiplying gives a minus giving:
$+ 1 \times (- 1) = - 1$ $color(magenta)(+1)color(green)(xx(-1))color(blue)( = -1)$
