This example dynamically demonstrates the geometric meaning of integer multiplication, visually showing the relationship between products and points on the number line. Core math concepts include integers, multiplication, number line, geometric distribution, and sequences. Construction highlights involve GeoGebra commands like Segment, Distance, Angle, and objects such as B, O, A, A_1, B_1, f, g_1, AB, α, C, h, OC, text1, text3, text2, text4, a, b, e, x_1, y_1, D, g, E, β, OD, OA1, i, c, d for parametric construction and labeling. Suitable for middle school and above mathematics education to understand the geometric representation of multiplication and sequence patterns.

GeoGebra Commands & Parameters

  1. Segment(A_1, O) → f
  2. Segment(B_1, O) → g_1
  3. Distance(A_1, B_1) → AB
  4. Angle(A_1, O, B_1) → α
  5. Segment(O, C) → h
  6. Distance(O, C) → OC
  7. Segment(D, O) → g
  8. Angle(E, O, D) → β
  9. Distance(O, D) → OD
