La '''numeració àtica''' era utilitzada en l'[[antiga Grècia]], possiblement des del segle VII aband de crist. També és coneguda com a la '''numeració herodianica''' perquè va ser descrita per primera vegada en un manuscrit del segle II per [[Aelius Herodianus|Herodian]]. També es coneguda com a '''numeració acrofonica''' ja que tots els símbols usats, excepte el del nombre '1', deriven de la primera lletra de les paraules ''cinc'', ''deu'', ''cent'', ''mil'' i ''deu mil'' en grec.

A diferència de la més familiar [[numeració romana]] moderna, la numeració àtica només conté formes additives. Per exemple, el nombre 4 és escrit com ''ΙΙΙΙ'', igual que en la numeració romana antiga, no com en la numeració romana medieval i moderna que s'escriuria ''IV''.
The use of Η for 100 reflects the early date of this numbering system: Η ([[Eta (letter)|Eta]]) in the early Attic alphabet represented the sound /h/. In later, "classical" Greek, with the adoption of the Ionic alphabet throughout the majority of Greece, the letter eta had come to represent the long e sound while the rough aspiration was no longer marked.<ref>See A.G. Woodhead "The Study of Greek Inscriptions, Second Edition" p.18: Cambridge University Press. ISBN 0-521-23188-X.</ref><ref>See Herbert Weir Smyth "Greek Grammar, Revised Edition" p.10 (§14): Harvard University Press. ISBN 0674362500.</ref> It wasn't until [[Aristophanes of Byzantium]] introduced the various accent markings during the Hellenistic period that the [[spiritus asper]] began to represent /h/. Thus the word for a hundred would originally have been written ΗEΚΑΤΟΝ, as compared to the now more familiar spelling {{polytonic|ἑκατόν}}. In modern [[Greek language|Greek]], the /h/ phoneme has disappeared altogether, but this has had no effect on the basic spelling.▼

▲In addition, numerals representing 50, 500, 5,000 and 50,000 són expressat per el símbol 'pi' antic (amb la pota dreta curta) i una tiny version of the applicable potència de deu. Per exemple, pi i delta combinats en un símbol representaven 50, pi i eta representaven 500.
