Four numbers. One target. Use every number once with +, −, ×, and ÷ to hit the answer. arithmetic is a simple mental math puzzle inspired by the classic 24 game. No timer, no noise, no extra game modes getting in the way. Just the numbers, the target, and that little moment when the solution finally clicks. How it works Each puzzle gives you four numbers and one target. Combine the numbers step by step until you land on the answer. Every number has to be used exactly once. Some puzzles are quick. Some look easy and then quietly ruin your confidence. Fractions and decimals are allowed, so the cleanest path is not always the first one you see. Four difficulty levels Easy Small numbers and friendly targets. Good for warming up. Medium Bigger numbers and more ways to get there. Hard Trickier targets, larger ranges, and plenty of dead ends. Expert Numbers up to 100 and targets up to 999. Not recommended if you hate being humbled by arithmetic. No impossible puzzles Puzzles are generated on your device and checked before you see them, so every board has at least one valid solution. XP and levels Earn XP for every solve, with more XP for harder puzzles. Level up over time and track your progress as the problems get tougher. Stuck? Use “how to solve” to see one valid path. It is there when you need it, not in your way when you do not.
