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

1 × 128 + 1 × 64 + 1 × 32 + 0 × 16 + 0 × 8 + 1 × 4 + 0 × 2 + 1 × 1 = 229

Read as powers of two: 128 + 64 + 32 + 4 + 1 = 229.
In historical numeral systems
Egyptian
2 coils of rope, 2 hobbles, 9 strokes
2 × 100 + 2 × 10 + 9 × 1 = 229. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 vertical wedges (sixties place), 4 corner wedges + 9 vertical wedges (units place)
3 × 60 + 49 = 229. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then kappa, then theta, marked as a numeral
sigma-kappa-theta + keraia
sigma + kappa + theta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
resh, then kaf, then tet
resh-kaf-tet
resh (200) + kaf (20) + tet (9) = 229, written in descending order.
Maya
2 bars + 1 dot (upper, twenties place) over 1 bar + 4 dots (lower, units place)
11 × 20 + 9 = 229. 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.
