Operations on a Number Line

Tyler Auer
This GeoGebra applet allows you to explore how the answer to an operation changes as you increase or decrease the operands. Drag the pink circles along the number line to change the values of the operands. Right is larger. Click the check boxes to turn the result of the labeled operation. For example, if you want to see where x / y falls on the number line, check the "Division" box.
