This example demonstrates the addition of integers on a number line. Key mathematical concepts include integer addition and number line representation. Using GeoGebra commands such as Segment, Line, and Vector, the addition process is visually illustrated. Suitable for high-grade elementary or junior high school students to learn integer addition and number line concepts.
