3-119.

Rewrite each of the following expressions using only addition. Then simplify the expression.

1.  $5 ( - 2 ) - 3$

$5\left(−2\right)+\left(−3\right) = −13$

1.  $7 - ( - 2 ) ( - 5 )$

Circling terms will also be helpful in this problem.

$7 - \enclose{circle}{ \ \ \ ( - 2 ) ( - 5 ) \ \ \ }$

1.  $- 7 + - 3 - ( - 5 )$

The equivalent addition expression is $−7+\left(−3\right)+5$. Remember to simplify.

1.  $( - 4 ) ( - 25 ) - 300$

Circling terms first will be helpful. This has been done for you.

$\enclose{circle}{\ \ \ ( - 4 ) ( - 25 )\ \ \ } - 300$
