This example demonstrates interactive subtraction flash cards. It involves core math concepts like subtraction operations and random element selection. Construction highlights include using GeoGebra commands RemoveUndefined to clear undefined objects and RandomElement to generate random selections, with objects like t, text1, button1, list1, list2, b, a, c, s, d, e, f, g, h, i, j, k, l, m, text4, text5, text2, text3, text7. Suitable for elementary mathematics teaching or self-learning.

GeoGebra Commands & Parameters

  1. RemoveUndefined(list1) → list2
  2. RandomElement(list2) → b
  3. RandomElement(list2) → a

AI Drawing Prompt Reference

Create a subtraction flash card with two random numbers a and b for subtraction. Use RemoveUndefined to clear undefined objects, then randomly select a and b from the remaining objects. Ensure the result of a-b is displayed.
