🎮 How to Play?
The Mental Math Challenge is a race against the clock designed to push your neurons to the limit:
- You start with 10 seconds on the clock.
- Solve the operation shown and type the result.
- Each correct answer adds points and gives you extra seconds.
- Watch out! Incorrect answers deduct valuable time.
- Difficulty increases progressively: simple addition -> subtraction -> multiplication -> mixed operations.
🧠 Techniques to Calculate Like Lightning ⚡
You don't need to be a genius, you just need to know the tricks:
Decomposition
Break down large numbers. For 47 + 35, think: (40 + 30) = 70, and (7 + 5) = 12. Then 70 + 12 = 82.
Rounding and Compensation
If adding 19, add 20 and subtract 1. Example: 56 + 19 → 56 + 20 - 1 = 76 - 1 = 75.
Multiplying by 5
It's the same as multiplying by 10 and dividing by 2. Example: 14 x 5 → 140 / 2 = 70.
Exact Divisions
144 ÷ 12? Think reverse multiplication: what number times 12 gives 144? It's 12.
