Description: In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others.
Description: Named after mathematician Leonhard Euler, Euler's identity is known as a prime example of mathematical beauty because it links the four most fundamental constants in mathematics: the circle constant pi, Euler's number e, the imaginary unit i, as well as the numbers 1 and 0. It also features three basic arithmetic operations: addition, multiplication and exponentiation. This Japanese-language design features the famous equation along with its Japanese name ("oiraa no toushiki"). Wear this design to show your appreciation for the beauty of mathematics or buy it as a gift for your favorite math otaku and Japan enthusiast because nothing is more beautiful than math.
