![]() Wallis (1655) had proposed the symbol $\infty$ for infinity. \varsigma' &\delta^$, and the symbol $o$ for an infinitesimal increment. Diophantus (probably 3th century A.D.) denoted the unknown $x$ and its powers by the following symbols: The rudiments of letter notation and calculus appeared in the post-Hellenistic era, thanks to the liberation of algebra from its geometric setting. In the mathematics of classical Antiquity, however, no operations were carried out on letters and such a letter calculus did not materialize. This mode of notation could potentially have developed into a calculus of letters. Dating from Archimedes (287–213 B.C.), the latter device became standard. In Euclid's Elements (3th century B.C.), quantities are denoted by two letters, the initial and final letters of the corresponding segment, and sometimes by one letter. Arbitrary quantities (areas, volumes, angles) were represented by the lengths of lines and the product of two such quantities was represented by a rectangle with sides representing the respective factors. The first mathematical symbols for arbitrary quantities appeared much later (from the 5th-4th centuries B.C.) in Greece. The most ancient systems of numbering (see Numbers, representations of) - the Babylonian and the Egyptian - date back to around 3500 B.C. The first mathematical symbols were signs for the depiction of numbers - ciphers, the appearance of which apparently preceded the introduction of written language. The development of mathematical notation was intimately bound up with the general evolution of mathematical concepts and methods.
