'''Francois Viete''' (1540-1603) was a [[French]] [[mathematician]] who introduced convenient notations for [[algebra]]ic formulas, like "x" and "y" in mathematical equations.  For example:

<math>2x + 3y = 3</math>

<math>2x + 3y = 3</math>

Viete inspired fellow French mathematician [[Rene Descartes]], who then developed a coordinate system for graphing such equations.
