Leonhard Euler made many contributions to math but the one thing he is most famous for is changing the base of the natural logarithim by using the letter e which is aka Euler's number
Euler created the symbol.
Leonhard Paul Euler
they have to know math how to use high tech skills
Calculus and Graph Theory.
Euler made many contributions to virtually every area of math. His complete works fill a whole library shelf. You might say he invented graph theory.
A polyhedron is a math formula and information about it can be found in a math textbook or on Math Is Fun, Euler's Polyhedron Formula, Math Munch and Open Study.
http://www.usna.edu/Users/math/meh/euler.html that is a website on him Leonhard Euler was a Swiss mathematician who made extensive contributions to a wide range of mathematics and physics. Euler is also the name of a type of mathematical software.Eulers rule is: F+V-2=E f=faces, v=verticies, e=edges
Leonhard Euler, a aswiss mathematician, started to use the letter e for the constant in 1727. The first book mentioning it is Euler's Mechanica (1736)
