VectorCoordinate GeometryGeometric Construction
This example demonstrates addition on a number line. Key mathematical concepts include the number line, vectors, and points. Using GeoGebra commands such as Point, Vector, and Text, the process of addition is dynamically illustrated. Suitable for high-grade elementary or junior high school students learning addition on a number line.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Vector(A, C) → u
  3. Vector(C, D) → v
  4. Text("+") → text2
  5. Text("-") → text3

AI Drawing Prompt Reference

Draw a number line starting from the origin, place points A, C, and D to represent the numbers 1, 3, and 5 respectively. Place a plus sign and a minus sign between points C and D to indicate the addition of vectors u and v.
