Math Brain Trainer

Math Brain Trainer is a fast-paced sprint: you have 60 seconds to solve as many arithmetic problems as you can. Correct answers are accepted the instant you type them, so the pace is entirely up to you. A wrong answer costs two seconds, which keeps accuracy just as important as speed.

The difficulty controls the operations: Easy uses addition and subtraction, Medium adds multiplication, Hard adds division, and Expert mixes multi-step problems and squares.

1. Choose a difficulty and press Start the 60-second sprint (or Enter).
2. Type the answer to each problem. Correct answers are accepted automatically.
3. Press Enter or Submit to check an answer you are unsure of. A wrong answer removes two seconds.
4. When time runs out, your score is the number of correct answers. Your best score for each difficulty is saved.

• Make tens: 47 + 38 = 47 + 3 + 35.
• Count up to subtract: 92 − 57 → 57 + 3 = 60, + 32 = 92, answer 35.
• Split multiplications: 14 × 6 = 60 + 24.
• Think of division as multiplication: 84 ÷ 7 → "seven times what is 84?"
• Accuracy first. Two seconds is longer than a quick check.
