In the Solve It, you classified sets of emoticons. In this lesson, you will classify real numbers into special subsets.

Essential Understanding The set of real numbers has several special subsets related in particular ways.

Algebra involves operations on and relations among numbers, including real numbers and imaginary numbers. (You will learn about imaginary numbers in Chapter 4.) Rational numbers and irrational numbers form the set of real numbers.

You can graph every real number as a point on the number line.

A number line has the points negative 4, negative 1 and 1 over 2, 0, radical 5, and 4.
