You've found Leonardo da Vinci's secret vault, secured by a series of combination locks. Fortunately, your treasure map has three codes: 1210, 3211000, and. . . hmm. The last one appears to be missing. Can you figure out the last number...

An unbelievable play on an American football field is the perfect backdrop for understanding crucial physics concepts. Michelle Buchanan goes play-by-play on the vectors, the scalars, and the glory of a downright scientific touchdown.

Have you ever come across an oddly stretched image on the sidewalk, only to find that it looks remarkably realistic if you stand in exactly the right spot? These sidewalk illusions employ a technique called anamorphosis - a special case...

Dutch artist Piet Mondrian's abstract, rectangular paintings inspired mathematicians to create a two-fold challenge. Can you solve the puzzle and get to the lowest score possible? Gordon Hamilton shows how.

What do Euclid, 12-year-old Einstein, and American President James Garfield have in common? They all came up with elegant proofs for the famous Pythagorean theorem, one of the most fundamental rules of geometry and the basis for...

When you're working on a problem with lots of numbers, as in economics, cryptography or 3D graphics, it helps to organize those numbers into a grid, or matrix. Bill Shillito shows us how to work with matrices, with tips for adding,...

There are aspects of computer code that look like language and some that seem more like algebra, and since we may be headed for a future where many people will need to learn to code, researchers are interested in figuring out how exactly...

Stories of discovery and invention often begin with a problem that needs solving. Summoned by the king to investigate a suspicious goldsmith, the early Greek mathematician Archimedes stumbles on the principle that would make him famous.

In this video we are going to explore a great question that many students struggle with in solving trigonometric equations.

In this video, I demonstrate how to factor a quadratic equation with large numbers, specifically (3n^2) - 2n = 645. We'll break down the 645 number and apply various factoring techniques to solve this equation. This will help you...
