Where 924 fits
Why 924 is special
Volkswagen cancelled the project, Porsche bought it back, and the resulting car was criticised for years for using components it was always designed around.

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

Read as powers of two: 512 + 256 + 128 + 16 + 8 + 4 = 924.
In historical numeral systems
Egyptian
9 coils of rope, 2 hobbles, 4 strokes
9 × 100 + 2 × 10 + 4 × 1 = 924. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 5 vertical wedges (sixties place), 2 corner wedges + 4 vertical wedges (units place)
15 × 60 + 24 = 924. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then kappa, then delta, marked as a numeral
sampi-kappa-delta + keraia
sampi + kappa + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then tav, then qof, then kaf, then dalet
tav-tav-qof-kaf-dalet
tav (400) + tav (400) + qof (100) + kaf (20) + dalet (4) = 924, written in descending order.
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.
