Integer Addition Interactive Demo: Vectors and Input Boxes

① This GeoGebra example demonstrates integer addition through an interactive visual, using vectors and input boxes to dynamically show the sum of two integers. ② The core mathematical concept is integer addition, involving natural numbers and integers, represented geometrically via vectors to bridge arithmetic and visual understanding. ③ Construction highlights: from the summary, Vector commands create vectors (u, v), Textfield and InputBox1/InputBox2 provide user input, objects include a, b, A, B, C, c, d, with text1-text4 displaying values and results, forming an interactive addition environment. ④ Suitable for upper elementary to middle school students learning integer rules, and for teachers demonstrating addition concepts in class, enhancing number sense and operational intuition.
