CCXCIX uses the subtractive pair IX: one before ten — ten minus one.
Binary
1 0 0 1 0 1 0 1 1
1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 0 × 16 + 1 × 8 + 0 × 4 + 1 × 2 + 1 × 1 = 299

4 × 64 + 5 × 8 + 3 × 1 = 299
Hexadecimal
1 2 b
1 × 256 + 2 × 16 + b × 1 = 299
Read as powers of two: 256 + 32 + 8 + 2 + 1 = 299.
In historical numeral systems
Egyptian
2 coils of rope, 9 hobbles, 9 strokes
2 × 100 + 9 × 10 + 9 × 1 = 299. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
4 vertical wedges (sixties place), 5 corner wedges + 9 vertical wedges (units place)
4 × 60 + 59 = 299. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then koppa, then theta, marked as a numeral
sigma-koppa-theta + keraia
sigma + koppa + 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 tsadi, then tet
resh-tsadi-tet
resh (200) + tsadi (90) + tet (9) = 299, written in descending order.
Maya
2 bars + 4 dots (upper, twenties place) over 3 bars + 4 dots (lower, units place)
14 × 20 + 19 = 299. 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.

The Faroe Islands and Greenland are both under the Kingdom of Denmark and both outside the European Union — the Faroes declined to join in 1973 and Greenland left in 1985, over fishing rights in each case.
