This example demonstrates signed numbers using arrows. It involves core math concepts like signed numbers, number line, and direction. Construction uses commands Sequence and Text with objects like a, list1, b, list2, etc. Ideal for middle school and above to visualize and understand signed numbers in a geometric context.

GeoGebra Commands & Parameters

  1. Sequence(Vector[(t, 0), (t + 1, 0)], t, 0, a - 1) → list1
  2. Sequence(Vector[(a + t, 0), (a + t + 1, 0)], t, 0, b - 1) → list2
  3. Sequence(Vector[(a, 2), (a - t, 2)], t, 1, b) → list4
  4. Text(b, (MeanX[list4], 2), false, true) → text2
  5. Sequence(Vector[(-t, 0), (-(t + 1), 0)], t, 0, a - 1) → list5
  6. Sequence(Vector[(-a, 2), (-(a - t), 2)], t, 1, b) → list6
  7. Sequence(Vector[(t, 0), (t + 1, 0)], t, 0, a - 1) → list1copy
  8. Sequence(Vector[(-t, 0), (-(t + 1), 0)], t, 0, a - 1) → listaneg2
  9. Sequence(Vector[(-a, 0), (-a - t, 0)], t, 1, b) → bnegativelist

AI Drawing Prompt Reference

Draw a number line starting from 0, and draw a series of 1-unit arrows to the right to represent positive numbers; then draw a series of 1-unit arrows to the right from a variable point a to represent positive numbers; next, draw a series of 1-unit arrows upwards from a to represent positive numbers; then draw a series of arrows to the left to represent negative numbers; finally, draw a series of arrows to the left from 0 to represent negative numbers, and draw a series of arrows to the left from a to represent negative numbers.
