Number Line with Definite Integral and Arithmetic Operations

This GeoGebra example constructs an interactive number line to visually demonstrate definite integrals, vectors, segments, and arithmetic operations. The core mathematical concepts include points and vectors on a number line, the geometric interpretation of definite integrals as areas, and arithmetic operations controlled by sliders or inputs. The construction uses GeoGebra commands such as Vector, Segment, and Point, creating objects like int1, int2 (possibly integral intervals or values), separator, u, v, w (vectors), a, b, d, e, f (numbers or points), A, B, C, D, E, F (points), and numerous text objects (text1 to text21) for displaying values and hints. This example is suitable for high school or early college students learning calculus, helping them connect definite integrals with number lines, vectors, and arithmetic operations. It can serve as a classroom demonstration or a self-study tool.
