Math originated during the prehistoric times, however, there is no proof of its first use. Most of the mathematical discoveries were a result of necessity. Humans in the prehistoric times mainly dealt with food and its equal division among their community. The study of complex mathematics was not found until around 3000 BC. The use of arithmetic, algebra and geometry was made by Babylonians and Egyptians for building and construction, as well as for astronomy.
At the beginning of the 6th Century BC, Greek mathematics was introduced by the ancient Greeks. A Greek Mathematician, Euclid presented the axiomatic method which is still prevalent in math today, comprising definition, axiom, theorem and proof. The concepts of surface area and volume of solids of revolution, the area under the arc of a parabola with the summation of an infinite series were explained by Archimedes.
The answer to the above question is, disappointingly, everyone and no one at the same time as the contribution of several topics and its interpretation was done by scientists from various parts of the world.
