Mastering the fundamentals isn't about being a genius; it's about being consistent. This 10-question sprint is designed for daily repetition until your response time is near-instant.

Drill Tip: If you're stuck on subtraction like $100 - 43$, try the 'Bridge to 10' method. Subtract to the nearest ten first ($100 - 40 = 60$), then take away the remainder ($60 - 3 = 57$). It’s much faster than carrying digits in your head.

Complete these mentally. No calculators, no fingers—just your brain and the clock.

Track your progress to see your growth over the week. Aim to beat your 'Time Taken' every day while keeping your score at 10/10.
