Page "Diophantus" Paragraph 36

Although Diophantus made important advances in symbolism, he still lacked the necessary notation to express more general methods.

This caused his work to be more concerned with particular problems rather than general situations.

Some of the limitations of Diophantus ' notation are that he only had notation for one unknown and, when problems involved more than a single unknown, Diophantus was reduced to expressing " first unknown ", " second unknown ", etc.

in words.

He also lacked a symbol for a general number n. Where we would write, Diophantus has to resort to constructions like: ... a sixfold number increased by twelve, which is divided by the difference by which the square of the number exceeds three.
