$- 24$
$24$
$11$
$- 5$

Show the worked steps

$Different$ $signs$ $give$ $a$ $negative$ $product.$
$3 \cdot 8 = 24,$ $so$ $the$ $answer$ $is$ $- 24 .$

Answer: $- 24$

Example 2 · Divide Integers

What

number

divided

by

5

gives

- 12 ?

$- 7$
$- 17$
$60$
$- 60$

Show the worked steps

$Undo$ $the$ $division$ $by$ $multiplying:$ $5 \cdot (- 12) = - 60 .$
$Check:$ $\frac{- 60}{5} = - 12 .$

Answer: $- 60$

Example 3 · Simplify Expressions

Simplify:

12 - (- 6) \cdot 2

$0$
$36$
$24$
$- 24$

Show the worked steps

$Multiply$ $first:$ $(- 6) \cdot 2 = - 12 .$
