= 500.
[2411.] Of the two methods of writing the symbols for 4, 9, 14, 19, &c., the method by subtraction (IV, IX, XIV, XIX, &c.) is rarer, and is characteristic of private, not public inscriptions.
[Some Forms of Numerals.]
[2412.] quīnctus, the older form of quīntus ([170, 4]) is sometimes found in old and even in classical writers. Instead of septimus and decimus, the older septumus and decumus are not uncommon ([28]).
[2413.] In the ordinals from twentieth upwards, the older forms vīcēnsumus or vīcēnsimus, trīcēnsumus or trīcēnsimus, &c., &c., are not infrequently found instead of vīcēsimus, trīcēsimus, &c., &c. ([63]; [28]).
[2414.] In the numeral adverbs from quīnquiēns upwards, later forms in -īēs ([63]) are often found: as, quīnquiēs, deciēs, &c., &c.
[2415.] In cardinals and ordinals from thirteen to seventeen inclusive, the larger number sometimes comes first, and in cardinals et is sometimes used, though rarely in Cicero.
decem trēs, L. 37, 30, 7, thirteen. fundōs decem et trēs relīquit, RA. 20, he left thirteen farms. Rarely the smaller number comes first with et: as, dē tribus et decem fundīs, RA. 99, of the thirteen farms.
[2416.] Numbers from 18 to 99 inclusive which end in 8 or 9 are usually expressed by subtraction, as in the list ([2405]); less frequently (not in Cicero, rarely in classical writers) by addition: as, decem et octō, 4, 19, 4; decem novem, Ta. H. 2, 58.
