Where 1912 fits
Why 1912 is special
About 1,500 of roughly 2,220 aboard died, largely because the ship carried lifeboats for around half that number — which was more than regulations required. The disaster produced the international convention on safety of life at sea that still governs shipping.

1 × 1,000 + 9 × 100 + 1 × 10 + 2 × 1 = 1,912. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 1 vertical wedge (sixties place), 5 corner wedges + 2 vertical wedges (units place)
31 × 60 + 52 = 1912. 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.
