In historical numeral systems

Egyptian

1 lotus, 8 coils of rope, 9 hobbles, 4 strokes

1 × 1,000 + 8 × 100 + 9 × 10 + 4 × 1 = 1,894. 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), 3 corner wedges + 4 vertical wedges (units place)

31 × 60 + 34 = 1894. 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.
