In historical numeral systems
Egyptian
2 lotuses, 2 strokes
2 × 1,000 + 2 × 1 = 2,002. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 3 vertical wedges (sixties place), 2 corner wedges + 2 vertical wedges (units place)
33 × 60 + 22 = 2002. Places are separated by a space on the tablet, with the higher place written first.
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.
