UNCERTAIN ANSWERS
Name:

By convention, mathematical expressions are simplified according to the following
sequence:
• Parentheses
• Exponents
• Multiplication and Division (Left to Right)
• Addition and Subtraction (Left to Right)
1. Fix These Equations
None of the statements below is correct as written. Rewrite them, inserting
parentheses so that the resulting statements are correct equations.
(a) 12 − 8 · 1 + 7 = 32
(b) 8 − 15 + 6 ÷ 3 = 1
(c) 7 + 32 = 100
(d) 24 + 16 ÷ 8 − 4 = 10
(e) 20 ÷ 7 − 2 + 52 · 3 = 79

2. What could it be?
Place parentheses in different places in the expressions below to see how
many different values you can make for each expression. Find at least three
different values for each problem. Then try to find the largest and smallest
possible answers by strategically placing parentheses.
(a) 7 − 5 · 8 + 6 ÷ 2
(b) 4 + 9 − 6 ÷ 2 · 5 + 1
