This example demonstrates the process of traditional multiplication. The core mathematical concept involved is multiplication. Using GeoGebra commands such as Random, Mod, text1, text2, text3, button1, etc., the example dynamically shows the steps of multiplication. Suitable for high-grade elementary and junior high school students to learn multiplication.

GeoGebra Commands & Parameters

  1. Random(1, 12) → posna
  2. Random(1, 12) → posnb
  3. Random(10, 90) → a_3
  4. Random(10, 99) → a
  5. Random(10, a) → a_1
  6. Random(100, 999) → bb
  7. Random(100, bb) → bb_1
  8. Mod(bb_1, 10) → bbbb1
  9. Random(1000, 9999) → cc
  10. Random(1000, cc) → cc_1
  11. Mod(cc_1, 10) → cc1
