In historical numeral systems
Egyptian
1 lotus, 5 coils of rope, 9 strokes
1 × 1,000 + 5 × 100 + 9 × 1 = 1,509. 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), 9 vertical wedges (units place)
25 × 60 + 9 = 1509. 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.
