Diophantus of Alexandria

Diophantus of Alexandria (circa 200-284 AD) was an ancient Greek mathematician often referred to as the "father of algebra." He specialized in solving equations that require integer solutions, which are now known as Diophantine equations. His work, particularly the book "Arithmetica," laid the groundwork for number theory, exploring how to find whole number solutions to complex problems. Diophantus introduced algebraic notation and techniques that influenced later mathematicians. His approach to equations was revolutionary for his time, merging arithmetic with algebra and leading to deeper investigations into the properties of numbers.
