Simplify the following expressions.

1.  $−5+(−3)$

For parts (a), (b), and (c), try drawing a diagram with $+$ and $−$ symbols if you are having difficulty.

1.  $6+(−3)$

1.  $−11−2$

1.  $4+(−10)$

Parts (d) and (e) are similar to (a) - (c).

1.  $3−(−9)$

1.  $(−2)(−5)$

Remember that the product of two negative integers is positive.

$10$

1.  $(5)(−16)$

If you had $5$ groups of $16$ negatives, how many negatives would you have?

1.  $−20\div5$

What would you need to multiply by $5$ to get $−20$?

$−4$

1.  $−12\div(−1)$

If you had $12$ negatives and you divided them into groups with one negative in each, how many groups would you have?
