Introduction to Using a Problem Solving Strategy

Highway into a city at night A clear strategy can put you on the fast track to solving word problems.
Equations, when used in our everyday lives, tends to be harder to solve because of their difficult wording. Numbers are generally spoken or delivered through written word. For example, how long would it take me to drive 10 miles if I am going 65 miles per hour? This chapter will teach you strategies when approaching word problems with no obvious equation, as well as how to apply these strategies to number problems.  

Learning Outcomes

By the end of this section, you will be able to:
  • Approach word problems with a positive attitude
  • Use a problem solving strategy for word problems
  • Solve number problems
  Before you get started in this module, try a few practice problems and review prior concepts.
