👉 Decurions are a type of mathematical representation used in various branches of mathematics, particularly in algebra and number theory. They were first introduced by Carl Friedrich Gauss in 1805 as part of his work on the theory of quadratic forms. A decurion is a binary operation that takes two elements x and y and produces a third element z such that: x + y = z z2 = x + y This means that the sum of x and y equals z, and
