Rules for Multiplying Integers

A power indicates how many times a number is multiplied by itself.

In this case, we will be multiplying $- 2$ $-2$ by itself three times.

${(- 2)}^{3}$ $(-2)^3$ $=$ $=$ $- 2 \times - 2 \times - 2$ $-2 times -2 times -2$

Now, multiply the first two values first.

A negative multiplied by a negative equals a positive number

$- 2 \times - 2$ $-2times-2$ $\times$ $times$ $- 2$ $-2$ $=$ $=$ $4$ $4$ $\times$ $times$ $- 2$ $-2$ Recall,

Finally, multiply the remaining values.

A positive multiplied by a negative equals a negative number

$4$ $4$ $\times$ $times$ $- 2$ $-2$ $=$ $=$ $- 8$ $-8$ Recall,

$- 8$ $-8$
