In historical numeral systems
Egyptian
3 coils of rope, 7 hobbles, 3 strokes
3 × 100 + 7 × 10 + 3 × 1 = 373. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
6 vertical wedges (sixties place), 1 corner wedge + 3 vertical wedges (units place)
6 × 60 + 13 = 373. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then omicron, then gamma, marked as a numeral
tau-omicron-gamma + keraia
tau + omicron + gamma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then ayin, then gimel
shin-ayin-gimel
shin (300) + ayin (70) + gimel (3) = 373, written in descending order.
Maya
3 bars + 3 dots (upper, twenties place) over 2 bars + 3 dots (lower, units place)
18 × 20 + 13 = 373. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.
