This interactive exercise demonstrates how basic inequalities A < B or A > B remain unchanged or are reversed when multiplied by a positive or negative number k. Key concepts include the properties of inequalities and multiplication. Using GeoGebra commands such as Textfield, Function, and Sequence, this example dynamically illustrates this mathematical concept. Suitable for middle school and above students studying inequality transformations.

GeoGebra Commands & Parameters

  1. Textfield(ticksize) → inputBox3
  2. Textfield(lowerbound) → inputBox1
  3. Textfield(upperbound) → inputBox2
  4. Function(0, lowerbound - 0.5, upperbound + 0.5) → numline
  5. Function(ticksize / 4, lowerbound - 0.5, upperbound + 0.5) → abovenumline
  6. Sequence((i, 0), i, lowerbound, upperbound, 1) → listTicks
  7. Sequence(Text[i, (i - ticksize / 5, -0.95)], i, lowerbound, upperbound, ticksize) → ListxaxisNumbers
  8. Point(abovenumline) → A_d
  9. Point(abovenumline) → B_d
  10. If(p_{boolean} ≟ true, Random[lowerbound, upperbound], x(A_d)) → x_A
  11. If(p_{boolean} ≟ true, Random[lowerbound, upperbound], x(B_d)) → x_B
  12. Textfield(k) → inputBox4
  13. CircumcircleArc(A, M_{A'A}, A') → c
  14. CircumcircleArc(B, M_{B'B}, B') → d

AI Drawing Prompt Reference

Draw a number line with tick marks and a horizontal line. There are two points A and B above the horizontal line. A circular arc is drawn above the line, related to points A and B. The figure should clearly show the points, lines, and arc and their positions.
