Mental math – short lessons, lasting progress.
A calm math course that starts with mental arithmetic: plus and minus up to 20 and 100, the multiplication tables and larger numbers. Every correct answer pays crystals into your account, and reviews come up exactly when your memory needs them. More topics like fractions and percentages will follow as new units.
How it works
- Pick a unit and start a short lesson of eight exercises.
- Solve in your head and type the result – every answer is judged server-side.
- Correct answers strengthen your skills. Due reviews pay the most crystals – mindless grinding doesn't.
