Math teachers have stymied students for hundreds of years by sticking goats in strangely shaped fields. Learn why one grazing goat problem has stumped mathematicians for more than a century.

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. Here's the secret.

His secret is in generalizing two roots ... examples end up solving out to Pythagorean triples, the small set of integer values that work cleanly into the Pythagorean theorem. Quadratic equations are ...
