In historical numeral systems

8 lotuses, 6 coils of rope, 8 hobbles, 4 strokes

8 × 1,000 + 6 × 100 + 8 × 10 + 4 × 1 = 8,684. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

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.
