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

1 × 256 + 0 × 128 + 1 × 64 + 1 × 32 + 1 × 16 + 1 × 8 + 0 × 4 + 1 × 2 + 1 × 1 = 379

Hexadecimal

1 × 256 + 7 × 16 + b × 1 = 379
Read as powers of two: 256 + 64 + 32 + 16 + 8 + 2 + 1 = 379.
In historical numeral systems
Egyptian
3 coils of rope, 7 hobbles, 9 strokes
3 × 100 + 7 × 10 + 9 × 1 = 379. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
6 vertical wedges (sixties place), 1 corner wedge + 9 vertical wedges (units place)
6 × 60 + 19 = 379. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then omicron, then theta, marked as a numeral
tau-omicron-theta + keraia
tau + omicron + 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 ayin, then tet
shin-ayin-tet
shin (300) + ayin (70) + tet (9) = 379, written in descending order.
Maya
3 bars + 3 dots (upper, twenties place) over 3 bars + 4 dots (lower, units place)
18 × 20 + 19 = 379. 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.
