Read as powers of two: 512 + 128 + 64 + 8 + 4 + 1 = 717.
In historical numeral systems
Egyptian
7 coils of rope, 1 hobble, 7 strokes
7 × 100 + 1 × 10 + 7 × 1 = 717. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 1 vertical wedge (sixties place), 5 corner wedges + 7 vertical wedges (units place)
11 × 60 + 57 = 717. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then iota, then zeta, marked as a numeral
psi-iota-zeta + keraia
psi + iota + zeta 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 yod, then zayin
tav-shin-yod-zayin
tav (400) + shin (300) + yod (10) + zayin (7) = 717, 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.
