This example demonstrates the rules of signs in integer multiplication to help students understand the concept. Key math concepts include integer multiplication and sign rules. Construction highlights involve GeoGebra commands like Arc (arc), If (conditional), and Sequence (sequence), along with objects A, a, b, c, lista3, lista1, B, d, texto1, texto2, texto3, texto4. Suitable for middle school mathematics teaching to visually illustrate multiplication sign patterns.

GeoGebra Commands & Parameters

  1. Arc((x - a / 2)^(2) = a / 2, (0, 0), (a, 0)) → c
  2. If(b < 0, Sequence[(-a * n, 0), n, 0, -b], Sequence[(a * n, 0), n, 0, b]) → lista3
  3. Sequence(Semicircle[Element[lista3, n], Element[lista3, n + 1]], n, 1, abs(b)) → lista1
