Integer Addition on the Number Line by ehock

This example visually demonstrates the process and result of integer addition on a number line through dynamic visualization. Core mathematical concepts include number line, integers, addition operation, vectors, and line segments. GeoGebra commands like Vector and Segment are used to construct vectors a, b, u, v, and objects A, B, C, D, R, Z, g, h, i, r, and text1. It is suitable for middle school mathematics education, helping students understand the geometric meaning of integer addition and enhancing their ability to combine numbers and shapes.
