Read as powers of two: 512 + 256 + 128 + 64 + 4 + 2 + 1 = 967.
In historical numeral systems
Egyptian
9 coils of rope, 6 hobbles, 7 strokes
9 × 100 + 6 × 10 + 7 × 1 = 967. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 6 vertical wedges (sixties place), 7 vertical wedges (units place)
16 × 60 + 7 = 967. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then xi, then zeta, marked as a numeral
sampi-xi-zeta + keraia
sampi + xi + 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 tav, then qof, then samekh, then zayin
tav-tav-qof-samekh-zayin
tav (400) + tav (400) + qof (100) + samekh (60) + zayin (7) = 967, 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.
