Where 755 fits
Why 755 is special
He passed Ruth in 1974 and held the record until 2007. Aaron never hit more than 47 in a season — the total came from twenty consecutive years of consistency rather than any peak.

In historical numeral systems
Egyptian
7 coils of rope, 5 hobbles, 5 strokes
7 × 100 + 5 × 10 + 5 × 1 = 755. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 2 vertical wedges (sixties place), 3 corner wedges + 5 vertical wedges (units place)
12 × 60 + 35 = 755. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then nu, then epsilon, marked as a numeral
psi-nu-epsilon + keraia
psi + nu + epsilon 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 shin, then nun, then he
tav-shin-nun-he
tav (400) + shin (300) + nun (50) + he (5) = 755, 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.
