      Creating More User-Friendly Algebraic Expressions

      Algebraic expressions involve terms (separated by addition and subtraction) and factors (connected by multiplication and division). Part of the challenge of working with algebraic expressions is in using the correct rules: the order of operations, rules of exponents, distributing, and so on. Function notation helps simplify some expressions by providing a rule and inviting evaluation.

The Problems You’ll Work On

      In this chapter, you get to put some of those algebraic rules to practice with the following types of problems:

       Finding the sums and differences of like terms

       Multiplying and dividing terms and performing the operations logically

       Applying the order of operations when simplifying expressions

       Evaluating algebraic expressions when variables are assigned specific values

       Using the factorial operation

       Getting acquainted with function notation

What to Watch Out For

      Here are a few more things to keep in mind:

       Recognizing like terms and the processes involved when combining them

       Reducing fractions correctly — dividing by factors
