About this app
Multiplication Formulas & Area Model is an interactive middle-school math app for exploring two identities with visual square and rectangle areas. Adjust a and b to investigate (a+b)² = a² + 2ab + b² and (a+b)(a−b) = a² − b², then test your understanding with multiple-choice challenges.
Use cases
- Middle-school students learning algebraic identities
- Teachers demonstrating formulas with visual area models
- Learners practicing perfect-square expansions
- Students reviewing difference-of-squares factorization
- Parents supporting at-home math study
Features
- Interactive area model for (a+b)² split into a², two ab pieces, and b²
- Interactive difference-of-squares model showing an a² square minus a b² square
- Adjustable a and b controls with calculated areas and formula breakdowns
- Four guided missions in each exploration section
- Four multiple-choice quiz problems with a correct-answer streak
