Guiding the course is , a professor of mathematics at Harvey Mudd College and a renowned professional magician. Dr. Benjamin blends cognitive science, classical arithmetic, and performance art. He demonstrates that lightning-fast calculation is a learned skill, not an innate genius. 🧠 Core Philosophy: The Left-to-Right Method

You might think you already know how to add. You are wrong. The course teaches you to "round up and then subtract." For example, adding 398 becomes adding 400 and subtracting 2. Subtraction is taught using the "Add the Complement" method to turn hard subtraction problems into easy addition problems.

Professor Benjamin is not your typical academic. He is a professional magician and a "mathemagician," known for his TED Talks and his ability to square five-digit numbers in his head faster than an audience member can type them into a calculator. His teaching style is infectious, blending rigorous mathematical proof with the showmanship of a performer. He doesn't just teach you how to do the math; he makes you fall in love with the beauty of the numbers themselves.

Multiplication is often a major bottleneck in mental processing. Dr. Benjamin solves this by teaching the and algebraic simplification . Guiding the course is , a professor of

The course demystifies multiplication by breaking it into digestible pieces. Benjamin introduces the concept of "addition-multiplication." To multiply a number by 99, for example, the course teaches you to multiply by 100 and subtract the original number. It seems obvious in hindsight, but under pressure, few think to do it.

Professor Benjamin bridges the gap between "pen and paper" speed and "pure mental" speed. You learn how to write down numbers in a specific way to reduce the number of carries you have to track. He demonstrates that lightning-fast calculation is a learned

: Assign consonant sounds to digits from 0 to 9.

: Multiply the first digit by the next consecutive integer, then append 25. For 75275 squared , calculate , resulting in Close-Together Numbers : Use the algebraic identity . To multiply , reframe it as . The problem becomes , which is 3. The Art of "Guesstimation" and Division
