Who named math Math?

Answer 1

In Europe it derived from the Greek mathematike. Mathematic was a singular noun until the late 14th Century, when mathematics started to replace it. By the 17th Century it was mathematics across the English speaking world. This was abbreviated to maths in most of the English speaking world but for some strange reason the US chose to go for math in the late 19th Century. The guilty individual has still to be identified!

Answer 2

Leonhard Euler
