Read as powers of two: 256 + 64 + 2 + 1 = 323.
In historical numeral systems
Egyptian
3 coils of rope, 2 hobbles, 3 strokes
3 × 100 + 2 × 10 + 3 × 1 = 323. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 2 corner wedges + 3 vertical wedges (units place)
5 × 60 + 23 = 323. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then kappa, then gamma, marked as a numeral
tau-kappa-gamma + keraia
tau + kappa + 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 kaf, then gimel
shin-kaf-gimel
shin (300) + kaf (20) + gimel (3) = 323, written in descending order.
Maya
3 bars + 1 dot (upper, twenties place) over 3 dots (lower, units place)
16 × 20 + 3 = 323. 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.
