In collections Exercise For Addition and Subtraction of Integers

① Demonstrates random generation of integer addition and subtraction quiz questions with instant feedback; ② Core math concepts: integers, addition, subtraction, arithmetic mean, vectors, natural numbers, combinatorics; ③ Construction highlights: uses GeoGebra commands Point, Random, Vector, Textfield, Mirror and objects f, g, A, B, a, b, C, D, u, v, button1, button2, c, InputBox1, text2, text1, d, D', w, n, text3; ④ Suitable for upper elementary to middle school practice, self‑study, or classroom demonstration.

GeoGebra Commands & Parameters

Point(f) → A
Point(g) → B
Random(-10, 10) → a
Random(-10, 10) → b
Vector(A, C) → u
Vector(B, D) → v
Textfield(c) → InputBox1
Mirror(D, x = x(B)) → D'
Vector(B, D') → w
Random(1, 2) → n

AI Drawing Prompt Reference

Create an integer addition and subtraction practice interface: place two random points on two separate lines in a coordinate plane, and generate two random integers as operands. Draw a vector from the first point to another random point, and a second vector from the second point to its mirror image across a vertical line. Include a text input box for answers, two buttons for generating new questions and checking answers, and display a random choice indicating whether the operation is addition or subtraction, with a feedback text area. The layout should be clear for educational demonstration.
