In historical numeral systems

Egyptian

1 lotus, 7 coils of rope, 2 hobbles, 7 strokes

1 × 1,000 + 7 × 100 + 2 × 10 + 7 × 1 = 1,727. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 8 vertical wedges (sixties place), 4 corner wedges + 7 vertical wedges (units place)

28 × 60 + 47 = 1727. 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.
