In historical numeral systems
Egyptian
2 coils of rope, 5 hobbles, 8 strokes
2 × 100 + 5 × 10 + 8 × 1 = 258. 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), 1 corner wedge + 8 vertical wedges (units place)
4 × 60 + 18 = 258. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then nu, then eta, marked as a numeral
sigma-nu-eta + keraia
sigma + nu + eta 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 nun, then het
resh-nun-het
resh (200) + nun (50) + het (8) = 258, written in descending order.
Maya
2 bars + 2 dots (upper, twenties place) over 3 bars + 3 dots (lower, units place)
12 × 20 + 18 = 258. 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.
