雀十大玩家 vs Mental Math Trainer

麻将合十消除游戏，挑战100关，雀实赢麻了！！！

CalcSprint is a mental math trainer built for one thing: making you faster at arithmetic in your head. No paper, no calculator — just you, the clock, and a stream of problems to solve as fast as you can. Every session is a timed sprint. The clock starts, problems appear, and you tap the correct answer. The quicker and more accurately you solve, the higher you score. How it works: • Timed sprints — solve as many problems as you can before time runs out • Pick your length — 30-second, 1-minute, or 2-minute sessions • Three levels — Easy (add and subtract), Medium (all four operations), Hard (all four, plus two-step problems) • Multiple choice — tap to answer and keep up the pace • Pure head math — quick single- and two-step calculations, done in your head Track your progress: • Streak of correct answers in a row • Accuracy — how many you get right • Average answer time — watch your speed climb • Your personal best, ready to beat • A 14-day history of your practice No account, no sign-up, no clutter — open the app and start solving in seconds. Made for students warming up before a test, anyone keeping their mental math sharp, and people who just enjoy quick calculation. Practice a little every day and your head math gets faster and more confident. Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
