This example demonstrates the process of multiplying negative numbers. Key mathematical concepts include the rules of negative number multiplication. Using GeoGebra commands such as Ellipse, Arc, Translate, and Mirror, the example dynamically illustrates the multiplication operation. Suitable for middle school and above students.

GeoGebra Commands & Parameters

  1. Ellipse((a / 2, sqrt(abs(4 - a^(2) / 4))), (a / 2, (-sqrt(abs(4 - a^(2) / 4)))), 2) → c1
  2. Arc(c1, (0, 0), (a, 0)) → left1
  3. Arc(c1, (a, 0), (0, 0)) → right1
  4. Translate(c1, Vector[(a, 0)]) → c2
  5. Translate(c2, Vector[(a, 0)]) → c3
  6. Translate(c3, Vector[(a, 0)]) → c4
  7. Translate(c4, Vector[(a, 0)]) → c5
  8. Arc(c2, ((a * 2), 0), (a, 0)) → right2
  9. Arc(c3, ((a * 3), 0), ((a * 2), 0)) → right3
  10. Arc(c4, ((a * 4), 0), ((a * 3), 0)) → right4
  11. Arc(c5, ((a * 5), 0), ((a * 4), 0)) → right5
  12. Arc(c2, (a, 0), ((2 * a), 0)) → left2
  13. Arc(c3, ((2 * a), 0), ((3 * a), 0)) → left3
  14. Arc(c4, ((3 * a), 0), ((4 * a), 0)) → left4
  15. Arc(c5, ((4 * a), 0), ((5 * a), 0)) → left5
  16. Mirror(c1, x = 0) → c6
  17. Mirror(c2, x = 0) → c7
  18. Mirror(c3, x = 0) → c8
  19. Translate(c8, Vector[((-a), 0)]) → c9
  20. Translate(c9, Vector[((-a), 0)]) → c10
  21. Arc(c10, ((-4 * a), 0), ((-5 * a), 0)) → left10
  22. Arc(c10, ((-5 * a), 0), ((-4 * a), 0)) → right10
  23. Ellipse((a / 2, sqrt(abs(4 - a^(2) / 4))), (a / 2, (-sqrt(abs(4 - a^(2) / 4)))), 4) → c
  24. Arc(c6, ((-a), 0), (0, 0)) → left6
  25. Arc(c7, ((-2 * a), 0), ((-a), 0)) → left7
  26. Arc(c8, ((-3 * a), 0), ((-2 * a), 0)) → left8
  27. Arc(c9, ((-4 * a), 0), ((-3 * a), 0)) → left9
  28. Arc(c6, (0, 0), ((-a), 0)) → right6
  29. Arc(c7, ((-a), 0), ((-2 * a), 0)) → right7
  30. Arc(c8, ((-2 * a), 0), ((-3 * a), 0)) → right8
  31. Arc(c9, ((-3 * a), 0), ((-4 * a), 0)) → right9

AI Drawing Prompt Reference

Draw an ellipse centered at the origin with semi-major axis a/2 and semi-minor axis the square root of 4's absolute value. Then draw two arcs with radius a, one from the origin to (a,0) and the other from (a,0) to the origin. Next, translate the ellipse and arcs to the right by a, and repeat this process four times. Then draw a mirrored ellipse and arcs centered at the origin with semi-major axis a/2 and semi-minor axis the square root of 4's absolute value. Draw two arcs with radius a, one from the origin to (-a,0) and the other from (-a,0) to the origin. Translate the mirrored ellipse and arcs to the left by a, and repeat this process four times.
