This GeoGebra applet visually demonstrates the solution and geometric meaning of the absolute value inequality |x| < a. By using sliders to control the parameter a, it dynamically displays the solution set as an interval on the number line (-a < x < a) and combines function graphs to help understand the concept of absolute value as distance. It is ideal for middle and high school students learning
