# MathMe > Scrolling that makes you smarter: a mental math course, 6 modes, 1-on-1 duels ## About MathMe is a mental math trainer built like a feed. One question per screen: tap the answer, swipe to the next. The minutes that would have gone to another feed go to a skill you keep for life. 39 topics in 7 chapters — Numeration, Whole Numbers, Divisibility, Common Fractions, Decimals, Ratios and Proportions, Percentages — with 1,334 practice questions. Each topic teaches one technique. ×5 is ×10 ÷ 2. ×25 is ×100 ÷ 4. You see how the trick works, why it is worth knowing and where people usually slip — then practice it right away in a feed you scroll through. The starter topics are free. The full course is part of MathMe Pro. In Duel you create a room and send the code to a friend, join a room by code, or let the app find an opponent. 10 rounds, one winner. Want to warm up first? Train against a bot — it does not affect your rating. ## Modes - Swipe — A timer on every question, a swipe to get the next one. Difficulty is matched to your skill level. Two hints help when it gets hard: 50/50 removes two wrong options, and the Shield protects you from your next wrong answer. - Duel — In Duel you create a room and send the code to a friend, join a room by code, or let the app find an opponent. 10 rounds, one winner.
