Description Play a round. Learn a trick. Watch your times drop. Most math apps just drill you. This one makes you faster — with the shortcuts, patterns, and Vedic math tricks your teacher never showed you. RACE THE CLOCK Solve as many problems as you can before time runs out. Four difficulties, from 45 seconds of small numbers to two full minutes of squares, roots, cubes and percentages. One wrong answer and your combo's gone. It's the kind of thing you open for "one quick round" and look up ten rounds later. LEARN THE TRICKS This is where it gets good. Twenty-five techniques along a trail, one stop at a time — see how it works, then prove it in a timed test to unlock the next. Green Foothills: the basics you'll lean on forever — making tens, doubling, ×5, ×9. Whispering Woods: a step up — rounding and adjusting, complements to 100, squares and roots, the ×11 shortcut. Frost Peaks: the real Vedic math — squaring anything ending in 5, multiplying near a base (Nikhilam), crosswise multiplication (Urdhva-Tiryagbhyam), ×99 in your head. Beat each region's boss round and the next one opens up. WEEKLY CHALLENGE A global leaderboard that wipes clean every Monday. Everyone starts level, everyone gets seven days. Find out where you actually rank. THREE GAMES, NOT JUST DRILLS Equation Tiles: a merge puzzle where the tiles are equations. "2×2" merges with "4". You have to do the math to spot the match. Falling Equations: solve them before they land. Miss three and you're out. Make the Target: combine four numbers with +, −, ×, ÷ to hit the number. Every puzzle is solvable. Finding it is the hard part. PRACTICE HOW YOU WANT Multiply & Divide: pick your own numbers and nail the times tables Add & Subtract: back to basics Weak Spot: hunts down whatever you keep getting wrong Zen: no timer, no pressure Sudden Death: three seconds a question, one slip and you're out Plus stats that actually mean something — accuracy, best streaks, day streaks — and a pile of achievements to chase. Get Math Expedition and find out how quick you really are.
