Integer Subtraction Distance Model

This example demonstrates the geometric interpretation of integer subtraction using a distance model on a number line, visually representing the operation of subtraction. Core mathematical concepts include number line, distance, linear equations, and vectors. Construction highlights involve using GeoGebra commands like Segment with objects such as n, i, s, text elements, and points A, B, A_1, etc., to plot the model. Suitable for middle school students and above to understand the geometric meaning of subtraction and introductory coordinate geometry.
