Basic Algebra/Working with Numbers/Integers and the Number Line
- Integer: A whole number (both positive and negative).
- Number Line: a line marked periodically with numbers
- Origin: Zero (0)
This number line shows the numbers from -10 to (positive) 10. Notice the arrows on either side to show that the numbers continue in both directions even though they are not shown on the line.
(Note: put answer in parentheses after each problem you write)
