In historical numeral systems

Egyptian

5 lotuses, 3 coils of rope, 8 hobbles, 9 strokes

5 × 1,000 + 3 × 100 + 8 × 10 + 9 × 1 = 5,389. 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.
