In historical numeral systems

Egyptian

1 lotus, 1 coil of rope, 5 hobbles, 7 strokes

1 × 1,000 + 1 × 100 + 5 × 10 + 7 × 1 = 1,157. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

1 corner wedge + 9 vertical wedges (sixties place), 1 corner wedge + 7 vertical wedges (units place)

19 × 60 + 17 = 1157. 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.
