In historical numeral systems
Egyptian
1 lotus, 9 coils of rope, 2 hobbles, 2 strokes
1 × 1,000 + 9 × 100 + 2 × 10 + 2 × 1 = 1,922. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 2 vertical wedges (sixties place), 2 vertical wedges (units place)
32 × 60 + 2 = 1922. 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.
