Where 318 fits
Why 318 is special

1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 1 × 16 + 1 × 8 + 1 × 4 + 1 × 2 + 0 × 1 = 318

Hexadecimal
1 3 e
1 × 256 + 3 × 16 + e × 1 = 318
Read as powers of two: 256 + 32 + 16 + 8 + 4 + 2 = 318.
In historical numeral systems
Egyptian
3 coils of rope, 1 hobble, 8 strokes
3 × 100 + 1 × 10 + 8 × 1 = 318. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 1 corner wedge + 8 vertical wedges (units place)
5 × 60 + 18 = 318. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then iota, then eta, marked as a numeral
tau-iota-eta + keraia
tau + iota + eta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then yod, then het
shin-yod-het
shin (300) + yod (10) + het (8) = 318, written in descending order.
Maya
3 bars (upper, twenties place) over 3 bars + 3 dots (lower, units place)
15 × 20 + 18 = 318. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.

Related numbers & connections
The A318 and A319 are both shortened A320s. Cutting length while keeping wing and engines produces excess range, which is why short variants become corporate aircraft.

Strength 0.50, confidence "high".
Technology & computing
The A318 service from London City stopped at Shannon westbound because London City's short runway prevented departure with a full load. Passengers cleared US customs during the stop, which turned a limitation into a feature.
