What 𐹰 means
It is the Rumi sign for eighty.
Rumi numerals, also called Fāsī, use separate signs for units, tens, and hundreds rather than place values.
From the 10th to 17th centuries, they served accounts, manuscript page and chapter numbering, scientific and mathematical works, and astronomical instruments across Egypt, the Maghreb, and al-Andalus. Manuscript quires—gatherings of folded sheets—could also be numbered this way.
Where did Rumi numerals come from?
They trace to Coptic or Greek-Coptic number traditions.
Coptic was the written language of Egypt’s Christian community. The earliest surviving written mention of rūmī signs is in an arithmetic book by the mathematician al-Uqlīdisī, completed in Damascus in 952–953; that is evidence, not an invention date.
Some scholars link Rumi/Fāsī numerals to Egyptian zimām numerals, used in administrative and commercial records among Christian, Muslim, and Jewish communities. Rumi/Fāsī forms appear in Toledo manuscripts in the 12th–13th centuries and later in Moroccan legal and commercial records.
