8-58.

Simplify the expressions below.

1.  $4 · 4 + 4\left(5 – 2\right) + 7$

For parts (a) through (d), refer to the Lesson 4.1.1 Math Notes box.

Remember to calculate the value for each term before adding!

The answer to part (a) is $35$.
Be sure to show your work!

1.  $7 – 9 ÷ 9 + 4\left(4 – 3\right) – 7$

The expression in parentheses should be simplified first.
Then remember to always multiply and divide before adding and subtracting.

1.  $–12 + 3\left(4 – 7\right) + \left(–5\right)$

Try circling the terms before simplifying the expression.
This way you will be less likely to make a mistake!

Be careful adding and subtracting negative integers!

1.  $–3\left(4 – 2 · 6\right) – 5$

Make sure you simplify the expression in parentheses first!

$19$
Don't forget to keep track of those negative integers!
