The Game of Arrows - Adding Signed Numbers

This example demonstrates the addition of signed numbers using dynamic arrows on a number line, visually illustrating the vector addition process. Core math concepts include signed numbers, number line, vector addition, and absolute value operations. GeoGebra commands like Point and Vector are used to dynamically control vector magnitude and direction, showing the addition process and calculating the absolute value of the sum. Suitable for middle school mathematics teaching to help students understand the geometric meaning and operational rules of signed number addition.
