In historical numeral systems
Egyptian
1 lotus, 2 coils of rope, 3 hobbles
1 × 1,000 + 2 × 100 + 3 × 10 = 1,230. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges (sixties place), 3 corner wedges (units place)
20 × 60 + 30 = 1230. 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.
