## What is Where It All Adds Up?

Where It All Adds Up is the only math app that shows every problem solved two ways — the way it's taught in United States classrooms and the way it's taught in Japan (日本) — side by side, so you understand the why, not just the answer.

Most solvers hand you one answer. This one teaches.

WHAT MAKES IT DIFFERENT
• Two methods, side by side — Compare the U.S. approach and the Japanese approach to the same problem and see how different classrooms think it through.
• Every step CAS-verified — A computer algebra system checks the work, so the steps are mathematically correct, never guessed.
• "Teach me" mode — Type each step yourself and get hints as you go. Learn to solve it — don't just copy it.
• Works fully offline — The entire math engine runs on your device. No account, no internet, nothing sent to a server.

WHAT IT SOLVES
Arithmetic & fractions, algebra & quadratics, systems of equations, calculus (derivatives & integrals), linear algebra (matrices, eigenvalues), word problems, and more — each worked step by step, both ways.

ALSO INSIDE
• Practice mode with generated problems and mastery tracking
• Graphing
• Snap a photo of a problem to bring it in

PRIVATE BY DESIGN
Your math never leaves your device. No sign-up. No ads. No tracking.

Whether you're a student trying to truly understand a method, a parent helping with homework, or just curious how the same problem is taught a world apart — Where It All Adds Up shows you where it all adds up.
