Why 750 is special

In historical numeral systems
Egyptian
7 coils of rope, 5 hobbles
7 × 100 + 5 × 10 = 750. 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 (units place)
12 × 60 + 30 = 750. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then nu, marked as a numeral
psi-nu + keraia
psi + nu 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
tav-shin-nun
tav (400) + shin (300) + nun (50) = 750, 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.
