In historical numeral systems
Egyptian
1 lotus, 8 coils of rope, 6 hobbles, 7 strokes
1 × 1,000 + 8 × 100 + 6 × 10 + 7 × 1 = 1,867. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 1 vertical wedge (sixties place), 7 vertical wedges (units place)
31 × 60 + 7 = 1867. 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.
