CCCXIV uses the subtractive pair IV: one before five — five minus one.

Read as powers of two: 256 + 32 + 16 + 8 + 2 = 314.
In historical numeral systems
Egyptian
3 coils of rope, 1 hobble, 4 strokes
3 × 100 + 1 × 10 + 4 × 1 = 314. 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 + 4 vertical wedges (units place)
5 × 60 + 14 = 314. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then iota, then delta, marked as a numeral
tau-iota-delta + keraia
tau + iota + delta 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 dalet
shin-yod-dalet
shin (300) + yod (10) + dalet (4) = 314, written in descending order.
Maya
3 bars (upper, twenties place) over 2 bars + 4 dots (lower, units place)
15 × 20 + 14 = 314. 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.
