This applet includes a (mostly) blank number line with two draggable variables (X and Y). Checkboxes allow the user to show the results of the addition, subtraction, division, multiplication, exponentiation, and radical operations.
This applet was created to help students explore how changing the value of an operand affects the results. For example, when studying multiplication of rational numbers, you can use this applet to explore when the product is greater than, between or less than the factors.
