In historical numeral systems
Egyptian
5 coils of rope, 7 hobbles, 8 strokes
5 × 100 + 7 × 10 + 8 × 1 = 578. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
9 vertical wedges (sixties place), 3 corner wedges + 8 vertical wedges (units place)
9 × 60 + 38 = 578. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
phi, then omicron, then eta, marked as a numeral
phi-omicron-eta + keraia
phi + omicron + eta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then qof, then ayin, then het
tav-qof-ayin-het
tav (400) + qof (100) + ayin (70) + het (8) = 578, written in descending order.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
