**Greek numerals** are a

system of representing numbers using letters
of the

Greek alphabet.

They are also known by
the names **Ionian numerals**, **Milesian
numerals** (i.e., from Miletus in Ionia), **Alexandrian numerals**, or
**alphabetic numerals**. In modern Greece, they are
still in use for ordinal
numbers, and in much the same situations as Roman numerals are in the West; for ordinary
(cardinal) numbers, Arabic numerals are used.
## History

Originally, before the adoption of the Greek alphabet,

Linear A and

Linear B had
used a different system with symbols for 1, 10, 100, 1000 and 10000
operating with the following formula: | = 1, – = 10, ◦ = 100, ¤ =
1000, ☼ = 10000.

The earliest alphabet-related system of numerals used with the
Greek letters was a set of the

acrophonic
Attic numerals, operating much like
Roman numerals (which derived from this scheme), with the following
formula: Ι = 1,
