FdeX

Mathematics, from primary school to university — explained, not just corrected. COURSES AND EXERCISES Over 50 complete courses: what it's for, the definitions, the method, worked examples, the classic pitfalls. Every course comes with fully corrected exercises, step by step. All of it works offline. LIVE CLASSES, TRANSLATED IN REAL TIME The teacher speaks, each student hears it in THEIR own language. The translation respects mathematical vocabulary: "Delta equals b squared minus 4ac" arrives correctly, not as unreadable symbols. Raise your hand, speak up, ask your question. SAM, THE TUTOR THAT EXPLAINS A question at any hour? SAM answers step by step, with properly written formulas. It doesn't just give the result — it shows the way. GET YOUR WORK CORRECTED Photograph your homework or send a PDF: the correction comes back detailed — what's right, what isn't, and why. KIDS' SPACE For younger children: learning to read, counting, shapes and games. The exercises genuinely match the level, from first grade upwards — measurements, fractions, decimals, two-step problems. PRIVATE LESSONS Need a real teacher?
