Speed Math EP20 - Impossible Edition | Eight Numbers, Twenty Seconds, No Paper

Nothing to write on, nothing to check against — only what you can keep in your head. Impossible Edition: five questions at Level 9 then five at Level 10, long chains, a 20-second clock. HOW IT'S SCORED: everything is calculated strictly left to right, like a calculator — NOT using BODMAS/PEMDAS order. 12 + 8 × 2 here is (12+8)×2 = 40. Drop your score in the comments — and if a specific question got you, quote it by its tag (EP20 Q7) so others can compare. A new challenge every day. Subscribe so tomorrow's set finds you. #SpeedMath #MentalMath #MathChallenge #MindMathAndYou #BrainTraining #MentalWorkout #NoCalculator #WorkingMemory #ImpossibleEdition
