Fundamental theorem of algebra The fundamental theorem of algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This includes polynomials with real coefficients, since every real number is a complex number with zero imaginary part. History[edit] Peter Rothe, in his book Arithmetica Philosophica (published in 1608), wrote that a polynomial equation of degree n (with real coefficients) may have n solutions. 7 fascinating TED Talks on the benefits of gaming This weekend, hundreds of video games enthusiasts lined up in the cold, waiting 12 hours-plus to be the first to get their hands on Nintendo’s new console, the Wii U. And when the game Call of Duty: Black Ops was released in 2010, gamers around the world played it for more than 600 million hours in just the first 45 days. That is the equivalent of 68 years.

Euclidean algorithm Euclid's method for finding the greatest common divisor (GCD) of two starting lengths BA and DC, both defined to be multiples of a common "unit" length. The length DC being shorter, it is used to "measure" BA, but only once because remainder EA is less than CD. EA now measures (twice) the shorter length DC, with remainder FC shorter than EA.
