Imaginary Number Hoodies

White Imaginary Number

You have a friend that LOVES math. Well, now you can show them you love them too! Also a great treat for yourself... specially if you do have an imaginary friend... I'm just saying

It's all fun and games until someone loses an eye--or an i, the imaginary number missing from this equation gone wrong. The perfect gift for math teachers, or for anyone who enjoys a geeky pun.

Math Joke Imaginary Unit Number Keeping It Real is great for those who like mathematics and other math subjects, or if you like the imaginary unit i specifically! Best for mathematicians and algebraists who love to share their interest in math. A great gift for math professors, teachers, students, and friends with math majors. Fun for those who like math, trigonometry, algebra, and calculus.

Say "Hi!" to my imaginary friend, the imaginary unit!

complex number

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.

The imaginary unit, i.

The imaginary unit, i.

The i, the imaginary number that makes the square root of a negative number possible has fallen. So naturally, it's all fun and games until someone loses an i.

Also know as Euler's identity. It combines the numbers 0, 1, pi, e, and i in one equation.
