In historical numeral systems
Egyptian
2 coils of rope, 2 hobbles, 7 strokes
2 × 100 + 2 × 10 + 7 × 1 = 227. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 vertical wedges (sixties place), 4 corner wedges + 7 vertical wedges (units place)
3 × 60 + 47 = 227. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then kappa, then zeta, marked as a numeral
sigma-kappa-zeta + keraia
sigma + kappa + zeta 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 kaf, then zayin
resh-kaf-zayin
resh (200) + kaf (20) + zayin (7) = 227, written in descending order.
Maya
2 bars + 1 dot (upper, twenties place) over 1 bar + 2 dots (lower, units place)
11 × 20 + 7 = 227. 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.
