In historical numeral systems
Egyptian
2 coils of rope, 6 hobbles, 9 strokes
2 × 100 + 6 × 10 + 9 × 1 = 269. 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 + 9 vertical wedges (units place)
4 × 60 + 29 = 269. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then xi, then theta, marked as a numeral
sigma-xi-theta + keraia
sigma + xi + theta 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 tet
resh-samekh-tet
resh (200) + samekh (60) + tet (9) = 269, written in descending order.
Maya
2 bars + 3 dots (upper, twenties place) over 1 bar + 4 dots (lower, units place)
13 × 20 + 9 = 269. 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.
