Where 396 fits
Why 396 is special
It replaced the 409 that had already been named in a hit record, which is a rare case of an engine's fame outlasting its production.

Roman numerals
C C C X C V I
CCCXCVI uses the subtractive pair XC: ten before a hundred — a hundred minus ten.
Binary
1 1 0 0 0 1 1 0 0
1 × 256 + 1 × 128 + 0 × 64 + 0 × 32 + 0 × 16 + 1 × 8 + 1 × 4 + 0 × 2 + 0 × 1 = 396
Octal
6 1 4
6 × 64 + 1 × 8 + 4 × 1 = 396
Hexadecimal
1 8 c
1 × 256 + 8 × 16 + c × 1 = 396
Read as powers of two: 256 + 128 + 8 + 4 = 396.
In historical numeral systems
Egyptian
3 coils of rope, 9 hobbles, 6 strokes
3 × 100 + 9 × 10 + 6 × 1 = 396. 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), 3 corner wedges + 6 vertical wedges (units place)
6 × 60 + 36 = 396. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then koppa, then stigma, marked as a numeral
tau-koppa-stigma + keraia
tau + koppa + stigma 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 tsadi, then vav
shin-tsadi-vav
shin (300) + tsadi (90) + vav (6) = 396, written in descending order.
Maya
3 bars + 4 dots (upper, twenties place) over 3 bars + 1 dot (lower, units place)
19 × 20 + 16 = 396. 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.
