    2.1 In Words
    In this section, we will show you how you can illustrate algebra in different ways.  We will go through two mathematical problems in four different ways:
    • In words
      We begin by expressing the problem in words.

    • Showing with figures
      A good way to try and illustrate a problem is by using pictures or figures.
    • Using tables
      Here you can try to put different numbers in a table and see if we get a pattern.

    • Stating as an algebraic expression
      We want to in the end be able to write a formula for the problem, and it is this that we call for writing an algebraic expression.

    We begin by expressing the problem in words:

    Example 2:

    Words
    Jasmine worked in the summer as a landscaper.  One day she was asked to plant 10 follows in a row.  In every row there was to be three flowers.

    How many flower sis Jasmine plant?
