1. Parentheses show us what part of the problem to do first .

 

 

Write parentheses in the following equations to make them true:

 

                 9 - 6 ÷ 3 = 1                                             4 x 2 + 1 = 12

 

                 9 - 6 ÷ 3 = 7                                             4 x 2 + 1 = 9

 

                20 ÷ 5 + 5 = 2                                           16 - 8 x 2 = 0

 

                20 ÷ 5 + 5 = 9                                           16 - 8 x 2 = 16

 

 2. When analyzing a 2-step problem, use parentheses to show which step you are doing first

 

 

Write and solve an equation for the following word problem:

 

 A suburban shopping mall has 105 rows of parking spaces with 45 spaces in each row. A special permit is required to park in 630 of those spaces.  How many spaces do not require a special permit?

 

 3. Watch out for sneaky questions that will give you too much information, or not enough information. Make sure that you are thinking through the questions carefully!
