Diophantus of Alexandria (c. 250 AD), an ancient Greek mathematician often called the "father of algebra," was the very first person known to use a dedicated symbol for an unknown quantity in equations, the direct ancestor of how we use “x” today.

Before this, mathematical problems were written out entirely in words.
