In historical numeral systems
Egyptian
5 coils of rope, 9 hobbles, 3 strokes
5 × 100 + 9 × 10 + 3 × 1 = 593. 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), 5 corner wedges + 3 vertical wedges (units place)
9 × 60 + 53 = 593. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
phi, then koppa, then gamma, marked as a numeral
phi-koppa-gamma + keraia
phi + koppa + gamma 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 tsadi, then gimel
tav-qof-tsadi-gimel
tav (400) + qof (100) + tsadi (90) + gimel (3) = 593, 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.
