Section 2.6 Literal Equations and Applications of Geometry 169 Calculator Connections Topic: Using the Key on a Calculator In Example 6 we could have obtained a more accurate result if we had used the p key on the calculator. Note that parentheses are required to divide 188.4 by the quantity This guarantees that the calculator follows the implied order of operations.Without parentheses, the calculator would divide 188.4 by 2 and then multiply the result by p. 2p.

On the back of each card, put the page number where you found that problem. Then shuffle the cards and test yourself on the procedure to solve each problem. If you find one that you do not know how to solve, look at the page number and do several of that type. Write four problems you would choose for this section.
