5-69.

Simplify each expression below.

1.  $\frac { - 4 } { 2 } + \frac { 12 } { - 4 }$

Remember that terms are separated by addition symbols ($+$). Can you circle the terms and simplify them before finding the final simplification?

1.  $\frac { - 4 + 12 } { 2 + ( - 4 ) }$

For part (b), simplify the expression on top of and below the division symbol before finally dividing.

$−4$

1.  $−17 − \left(−56\right)$

Subtracting a negative integer is actually like taking steps forward on a tightrope. It's also like undoing steps taken backwards. Does drawing a diagram help to simplify part (c)?

1.  $\left(−56\right)\left(−9\right)$

$504$

Were you able to find the answers to parts (a) and (c)? Remember to show your work!
