Coordinate Geometry Geometric Construction

This example demonstrates the addition and subtraction of positive and negative integers. Key mathematical concepts include integer addition and subtraction. Using GeoGebra commands such as RandomElement and Random, dynamic problems can be generated and visualized. Suitable for high-grade elementary or low-grade middle school students for practice.

GeoGebra Commands & Parameters

RandomElement({true, false}) → b
Random(-10, 10) → β
Random(-10, 10) → α
Vector(A, B) → u
Vector(C, D) → v
Vector(E, F) → w
Textfield(γ) → inputBox1
If(b ∧ α + β ≟ γ ∨ (¬b) ∧ α - β ≟ δ, 1, 0) → n
Textfield(δ) → inputBox2
Mirror(v, C) → v'
Vector(E, G) → z
