In historical numeral systems

Egyptian

1 lotus, 5 coils of rope, 3 hobbles, 3 strokes

1 × 1,000 + 5 × 100 + 3 × 10 + 3 × 1 = 1,533. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 5 vertical wedges (sixties place), 3 corner wedges + 3 vertical wedges (units place)

25 × 60 + 33 = 1533. 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.
