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

GeoGebra Commands & Parameters

  1. Vector(A, B) → u
  2. Vector(C, D) → v
  3. Segment(Z, A) → g
  4. Segment(B, C) → h
  5. Segment(D, R) → i
  6. Vector(Z, R) → w
  7. Vector(Z, R) → w_1
  8. Vector(A, B) → u_1
  9. Vector(C, D) → v_1
  10. Midpoint(C, D) → E
  11. Midpoint(A, B) → F
  12. Midpoint(Z, R) → G
