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.
