In historical numeral systems
Egyptian
1 lotus, 3 coils of rope, 2 hobbles
1 × 1,000 + 3 × 100 + 2 × 10 = 1,320. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 2 vertical wedges (sixties place), empty units place
22 × 60 + 0 = 1320. Places are separated by a space on the tablet, with the higher place written first. The second place is empty, and this is precisely the case the early system could not write unambiguously — the same wedges alone would also read as 1.
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.
