1 × 1,000 + 4 × 100 + 9 × 10 + 7 × 1 = 1,497. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 4 vertical wedges (sixties place), 5 corner wedges + 7 vertical wedges (units place)
24 × 60 + 57 = 1497. 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.
