Born during AD 200 and 214 to 284 or 289 Diophantus lived in Egypt during the Roman Era. Little is known about the early life of the mathematician as he was forgotten in Western Europe during the so-called dark ages. Majority of his work, in the form of books, has also not been recovered. Most of the knowledge about the mathematician has been derived from the 5th-century Greek anthology of number games and puzzles created by Metrodorus.

**What is the Arithmetica?**

Arithmetica is an ancient Greek text written by Diophantus in 3rd Century AD. It is a cluster of 130 Algebraic problems with numerical solutions of both determinate and indeterminate equations. It was originally composed as a set of 13 books, but only 6 books have survived.

The equations present in the text are known as Diophantine equations, and the methods of solving them are called Diophantine analysis.

A lot of mathematicians like Pierre de Fermat, Joseph-Louis Lagrange, and Leonhard Euler have worked on the contents of Arithmetica. It continues to have a profound impact on present-day mathematics.

**An example of a problem from the Arithmetica (sometimes called his epitaph) **

'Here lies Diophantus,' the wonder behold.

Through art algebraic, the stone tells how old:

'God gave him his boyhood one-sixth of his life,

One twelfth more as youth while whiskers grew rife;

And then yet one-seventh ere marriage begun;

In five years there came a bouncing new son.

Alas, the dear child of master and sage

After attaining half the measure of his father's life chill fate took him. After consoling his fate by the science of numbers for four years, he ended his life.'

According to the puzzle, Diophantus’ age can be expressed by the equation above. If solved, it yields 84 years. However, his actual age cannot be validated.

**What exactly is a Diophantine equation?**

A diophantine equation is a polynomial, with two or more variables. A diophantine equation can have variables with any power. Diophantine curves have more unknowns than equations, i.e. most of the variables have multiple values. This results in the formation of curves on a graph.

Diophantus was one of the first people to introduce symbolism to Algebra. The study of Diophantine equations, and finding their solutions is called Diophantine analysis.

**Diophantine Analysis: How to solve diophantine equations?**

Diophantine Analysis is the method of solving Diophantine Equations. A Diophantine Analysis is conducted with the following steps:

- Is it possible to get a solution?
- Is it possible to find solutions just by inspection?
- Are the number of solutions finite or infinite?
- Is it possible to obtain all the solutions?

**Death of Diophantus**

Diophantus is said to have died between AD 285 and 299.

**Summary**

This article talks about one of the greatest mathematicians to have graced the surface of the planet. His efforts and discoveries in algebra and number theory have been invaluable to advances in the field. Fermat’s last theorem, technique of adequality, maximas, minimas, and tangents of functions have all drawn inspiration from Diophantus’ work. The contributions he made have a profound impact on the world even today.
