Important Terms A mathematical phrase that contains only numbers and operations is called a numerical expression. To evaluate a numerical expression, you find its value. You can use the order of operations to evaluate a numerical expression.

Evaluate each expression.

Evaluate B. 4* 32 +8 -16

Evaluate C. 8 ÷ (1 + 3) * 52 - 2

NOW IT’S YOUR TURN! A) 15 – 10 ÷ 2 B) 8 + 14 ÷ 2 +6 * 32 C) 3 + (4 + 7) + 22

IN PAIRS! 5 * 3 +8 * 2 15 + 16 31

Closure: How would I evaluate this numerical expression? 5 – 6 ÷ 2 + 10 * 4
