Where 337 fits
Why 337 is special
Analogue circuits frequently need a symmetric supply, and the pairing of these two parts is the usual way to produce one.

In historical numeral systems
Egyptian
3 coils of rope, 3 hobbles, 7 strokes
3 × 100 + 3 × 10 + 7 × 1 = 337. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 3 corner wedges + 7 vertical wedges (units place)
5 × 60 + 37 = 337. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then lambda, then zeta, marked as a numeral
tau-lambda-zeta + keraia
tau + lambda + zeta 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 lamed, then zayin
shin-lamed-zayin
shin (300) + lamed (30) + zayin (7) = 337, written in descending order.
Maya
3 bars + 1 dot (upper, twenties place) over 3 bars + 2 dots (lower, units place)
16 × 20 + 17 = 337. 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.
