Glyphs for the ones, tens, and hundreds values are combined additively to form numbers, for example, ⰗⰑⰂ is 500 + 80 + 3 or 583.
As with Cyrillic numerals, between 11 and 19 the ordinary sign order is reversed, so the numbers 11 through 19 are typically written with the ones digit before the glyph for 10; for example ⰅⰊ is 6 + 10, making 16, this reflects the Slavic lexical numerals for the teens.
[6] There is also evidence of the use of a thousands sign, similar to the lower-left keraia in Greek numerals or the Cyrillic thousands sign to mark numbers greater than 999.
[3] For example, the Missale Romanum Glagolitice printed in 1483, uses both dots around and a titlo over letters in places to indicate a number,[7] as does the Vinodol statute.
Example: (·Ⱍ҃·Ⱄ҃·Ⱁ҃·) – 1280 As noted earlier, the letters associated with number values greater than 999 are uncertain, and different authors have inferred different values (and different orders) for letters towards the end of the Glagolitic alphabet.
