CMLXV uses the subtractive pair CM: a hundred before a thousand — a thousand minus a hundred.
Binary

Read as powers of two: 512 + 256 + 128 + 64 + 4 + 1 = 965.
In historical numeral systems
Egyptian
9 coils of rope, 6 hobbles, 5 strokes
9 × 100 + 6 × 10 + 5 × 1 = 965. 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), 5 vertical wedges (units place)
16 × 60 + 5 = 965. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then xi, then epsilon, marked as a numeral
sampi-xi-epsilon + keraia
sampi + xi + 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 tav, then qof, then samekh, then he
tav-tav-qof-samekh-he
tav (400) + tav (400) + qof (100) + samekh (60) + he (5) = 965, 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.
