In historical numeral systems
Egyptian
8 coils of rope, 8 hobbles
8 × 100 + 8 × 10 = 880. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 4 vertical wedges (sixties place), 4 corner wedges (units place)
14 × 60 + 40 = 880. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
omega, then pi, marked as a numeral
omega-pi + keraia
omega + pi 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 tav, then pe
tav-tav-pe
tav (400) + tav (400) + pe (80) = 880, 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.
