1 × 256 + 0 × 128 + 0 × 64 + 0 × 32 + 0 × 16 + 1 × 8 + 0 × 4 + 0 × 2 + 1 × 1 = 265

4 × 64 + 1 × 8 + 1 × 1 = 265
Hexadecimal
1 0 9
1 × 256 + 0 × 16 + 9 × 1 = 265
Read as powers of two: 256 + 8 + 1 = 265.
In historical numeral systems
Egyptian
2 coils of rope, 6 hobbles, 5 strokes
2 × 100 + 6 × 10 + 5 × 1 = 265. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
4 vertical wedges (sixties place), 2 corner wedges + 5 vertical wedges (units place)
4 × 60 + 25 = 265. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then xi, then epsilon, marked as a numeral
sigma-xi-epsilon + keraia
sigma + 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
resh, then samekh, then he
resh-samekh-he
resh (200) + samekh (60) + he (5) = 265, written in descending order.
Maya
2 bars + 3 dots (upper, twenties place) over 1 bar (lower, units place)
13 × 20 + 5 = 265. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.
