Welcome to Mind, Math & You — short daily challenges for your brain.

Speed Math: numbers flash once, you hold the running total in your head, and you answer before the clock runs out. No pen, no calculator, no pausing.

Everything is worked out left to right, calculator-style, not BODMAS. So 12 + 8 × 2 = 40.

Most days it's ten questions climbing from level 1 to level 10. Some days it isn't — Sprint gives you five seconds on every question, Impossible drops you straight into levels 9 and 10, and Marathon is three chains of twenty numbers each.

New episode every day.
