Rene Descartes

is responsible for having systematized our mathematical notation, using the letters at the end of the alphabet as variables, and those at the beginning as constants, and he brought into general use our present system of indices.

It should be remembered that it was Descartes who systematised our Mathematical notation. He used the letters at the end of the alphabet as variables, and those at the beginning as constants, and he brought into general use our present system of indices. He also introduced the method of indeterminate co-efficients for the solution of equations.
