Lesson 3 Summary

We use the words greater than and less than to compare numbers on the number line. For example, the numbers -2.7, 0.8, and -1.3, are shown on the number line.

Three points plotted on a number line and the numbers negative 3 through 3 are indicated. The numbers are as follows: Point 1: negative 2 point 7.  Point 2: negative 3 and negative 2. Point 3: zero point 8

Because -2.7 is to the left of -1.3, we say that -2.7 is less than -1.3. We write:

In general, any number that is to the left of a number  is less than .

We can see that -1.3 is greater than -2.7 because -1.3 is to the right of -2.7. We write

In general, any number that is to the right of a number  is greater than  

We can also see that  and . In general, any positive number is greater than any negative number.
