6-132.

Simplify each of the following expressions.

For parts (a), (b), and (c), refer to the Lesson 4.1.2 Math Notes box. The Order of Operations is very important when simplifying expressions.

1.  $\left(4 + 8\right) ÷ 12 + 23$

$24$

1.  $3 · \left(8 − 5\right) + 6 + 2 · 7$

Be sure to simplify the expression inside of the parentheses before multiplying from left to right.

$\enclose{circle}[mathcolor="orange"]{\color{black}{3 \cdot ( 8 - 5 )}} + \enclose{circle}[mathcolor="orange"]{\color{black}{(6)}} + \enclose{circle}[mathcolor="orange"]{\color{black}{ 2 \cdot 7 }}$

Make sure you carry out each multiplication operation before using addition! The terms are circled above.

1.  $49 ÷ 7 · 5 + 4 · \left(3 + 2\right)$

Have you circled the terms?

Make sure you read the Math Notes closely! It is important to multiply and divide from left to right, or you may simplify the expression incorrectly.
