In collections Multiplication Facts
This example demonstrates the nine's addition table and the frequency distribution of random variables in probability statistics. It involves core math concepts like addition operations, random variables, frequency distribution, and probability statistics. The construction summary utilizes GeoGebra commands and objects such as Random (random number generation), If (conditional logic), Shuffle (random shuffling), IndexOf (index searching), and LaTeX (formula rendering). It is suitable for middle school students and above to learn probability statistics and basic programming thinking.

GeoGebra Commands & Parameters

  1. Random(2, 12) → b
  2. Random(1, 2) → format
  3. If(b > 3, {"" + (c + floor(b / 2)) + "", "" + (c + ceil(a / 2)) + "", "" + (c - floor(b / 2)) + "", (("" * c) * "")}, {"" + (c - 1) + "", "" + (c - 2) + "", "" + (c + 1) + "", "" + c + ""}) → labelnums
  4. Shuffle(labelnums) → l1, {"30", "35", "25", "32"}
  5. IndexOf("" + c + "", l1) → d
  6. LaTeX(problemscorrect, true, true) → text4
  7. LaTeX(numberofproblems, true, true) → text3

AI Drawing Prompt Reference

Create a nine's addition table and a frequency distribution graph for probability statistics. First, generate two random numbers b and format, then based on the value of b, generate four related numbers. Next, randomly shuffle these four numbers, find the position of a specific number, and finally display the number of correct problems and total problems using LaTeX format.
