This example illustrates the concept of signed addition and subtraction. It involves key mathematical concepts such as vectors and linear functions. Using GeoGebra commands like Random and Vector, users can visually understand the geometric meaning of vector addition and subtraction. Suitable for students at the junior high school level and above.

GeoGebra Commands & Parameters

  1. Random(-6, 7) → first
  2. Random(-6, 7) → second
  3. Vector((0, 0), (first, 0)) → firstVec
  4. Vector((first, 0.5), (first + second, 0.5)) → secondVec
  5. Vector((first, 0.5), (first - second, 0.5)) → thirdVec
