Problem 1
This problem is designed to get you thinking about the procedure rather than the an answer.

Problems 2-11
In Chapters 1 and 2 we discussed estimating, and that theme is carried out with these problems. These problems are not intended to be pencil and paper problems, but rather are designed to get you thinking about "reasonable" answers. Don't be afraid to give these results your "best guess," and then check with the answer.

Problems 12-29
See Examples 1 and 2. These problems are a continuation of what you did in the last section, but you can not write down the answer. You need to focus on what you are doing to both sides of the given equations.

Problems 30-43
See Example 3.

Problems 44-51
See Example 4.

Problems 52-59
See Example 5.
