Where 359 fits
Why 359 is special
Bulgaria is where the Cyrillic alphabet was developed, and the country's EU accession made Cyrillic the third official script of the European Union alongside Latin and Greek.

CCCLIX uses the subtractive pair IX: one before ten — ten minus one.

1 × 256 + 0 × 128 + 1 × 64 + 1 × 32 + 0 × 16 + 0 × 8 + 1 × 4 + 1 × 2 + 1 × 1 = 359

Read as powers of two: 256 + 64 + 32 + 4 + 2 + 1 = 359.
In historical numeral systems
Egyptian
3 coils of rope, 5 hobbles, 9 strokes
3 × 100 + 5 × 10 + 9 × 1 = 359. 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), 5 corner wedges + 9 vertical wedges (units place)
5 × 60 + 59 = 359. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then nu, then theta, marked as a numeral
tau-nu-theta + keraia
tau + nu + theta 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 nun, then tet
shin-nun-tet
shin (300) + nun (50) + tet (9) = 359, written in descending order.
Maya
3 bars + 2 dots (upper, twenties place) over 3 bars + 4 dots (lower, units place)
17 × 20 + 19 = 359. 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.
