Chapter 2—Integers

2-2 Comparing Integer Values

 When you complete the work for this section, you should be able to: Demonstrate how to use the integer number line to compare integer values. Use the three comparison symbols to show the relative values of two integers. Explain how any negative integer is less than zero. Explain how any negative integer is less than any positive integer.

The values of integers increase from left-to-right along the number line.
The values of integers decrease from right-to-left along the number line.

The integer number line.

 Comparing Integers

Examples

 4 > 1 4 is greater than one. Why? Because 4 is located to the right of 1 on the integer number line. 0 < 3 0 is less than 3. Why? Because 0 is located to the left of 3 on the integer number line. – 1 <  4 – 1 (minus-one) is less than 4. Why? Because –1 is located to the left of 4 ( or + 4) on the integer number line. – 3  > – 5 – 3 (minus-three) is greater than minus – 5. Why? Because – 3 is located to the right of – 5 on the integer number line.
