Investigating Order of Operations
STEP 1: For each expression, describe the order of operations you would follow to get the value of the
expression. Use the phrases on the index cards to complete each row. Note that some expressions require two
operations and some require three.
STEP 2: Arrange your operation cards
Based on your results from Step 1, arrange your index cards to show the order of operations you should use
when you evaluate an expression.
STEP 3: Test your order
Use the order you created in Step 2 to complete the table. If your order does not result in the value shown,
revise the order of your index cards until it does.
DRAW CONCLUSIONS: Use your observations to complete these exercises.
1. Based on the order of your cards, what order of operations should you use to evaluate an expression?
Evaluate each expression.
2. 12 - (8 + 3)
4. 25 + 4 - 2
3. 5 + 3 x 2
5 . 4 + ( 14 - 6 )
Tell whether the statement is true or false. If it is false, give the correct value for the expression.
6. 10 + 3 x 7 = 91
7. 6 x 9 – 23 = 46
8. 6 + (12 ÷ 2) x 3 = 36
