Arithmetica is a fast and fun math game that challenges your mental agility! Solve as many equations as you can before time runs out — from simple addition to tricky multiplications.
Perfect for sharpening your math skills, improving reaction speed, or just testing how fast your brain can calculate.
With increasing difficulty and a race against the clock, Arithmetica turns numbers into an exciting challenge for players of all ages.
Each level presents you with a math equation or challenge — your goal is to select the correct answer as fast as possible.
Use the arrow keys to choose your answer (or click with the mouse on the correct one) before time runs out.
You only have a few seconds to answer. Think fast or it’s game over!
Correct answers give you points and move you forward. The further you go, the harder (and faster!) it gets.
Later levels mix in harder operations, trick questions, and number traps to keep you on your toes.
🧮 Master the Basics — brush up on addition, subtraction, multiplication, and division for a strong start.
🕒 Don’t Overthink It — trust your gut and go with your first instinct (most of the time).
🔁 Play in Rounds — replaying early levels helps build speed and confidence.
💡 Look for Patterns — some problems follow sneaky trends. Spotting them saves time.
❗ Stay Calm Under Pressure — panic = wrong answers. Stay cool, even with the clock ticking.
🧠 Train Daily — like any skill, quick math improves with consistent practice.
🎯 Accuracy Over Speed (at first) — better to answer right than fast… until you can do both!
