This lesson may have appeared too simple for you (and perhaps it was), but it serves as a foundation for the
lessons that follow. If you have learned other methods of solving these types of problems, you may use
them on tests; however, be sure that they work. If you missed any problem(s), review the appropriate
lesson frames and rework the problem(s) before going to the next lesson.
