Amazon Math

The same problem can reveal three different structures. Amazon Math contains 1,248 problems across 17 fields. Every problem places Gauss-, Euler-, and Ramanujan-inspired routes side by side, so you can compare why an idea works—not merely check the answer. Core experience: • Illustrated problems map the givens visually; others provide source-text reading guides • Zoom entity diagrams; explicitly linked elements highlight with their reasoning steps • Compare relative reading progress across three routes; morphing is limited to explicitly corresponding elements • Vote on whose solution feels most ingenious and say why • Find related practice in the same topic with shared tags and a similar difficulty • Solve first in a scratchpad, request hints, then compare all three approaches • 1,248 problems, 17 fields, and three difficulty levels The mathematicians represent teaching styles, not claims of historical authorship. Some routes are explorations or references to known theorems rather than standalone complete proofs. Privacy and offline use: No account, ads, analytics SDK, or third-party tracking. Progress stays on your device. The Simplified Chinese library is bundled with the app. English, Russian, German, Spanish, and French navigation is localized; problem text uses Apple’s on-device Translation and may require iOS to download a language model once.
