35 mental-math questions in 3:00. Mixed integers, decimals, fractions, missing operands.

A 3-minute sprint. Speed matters more than precision — if a question feels hard, skip and come back.

• Score: +1 correct, −1 wrong, −0.5 skipped.
• Pace: 12 per minute — one every 5 seconds. Anything slower and you'll run out of clock.
• Skip aggressively: If you can't see the answer in 3 seconds, skip. The score weighs a wrong twice as much as a skip.
• Speed > precision: Your goal is volume of correct answers, not perfection on every one.
• Format: Fractions like 7/16, decimals like 0.087. Enter submits, right answer auto-advances.
