In historical numeral systems
Egyptian
1 lotus, 1 coil of rope, 4 hobbles, 6 strokes
1 × 1,000 + 1 × 100 + 4 × 10 + 6 × 1 = 1,146. 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), 6 vertical wedges (units place)
19 × 60 + 6 = 1146. 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.
