In historical numeral systems
Egyptian
4 coils of rope, 6 hobbles, 6 strokes
4 × 100 + 6 × 10 + 6 × 1 = 466. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
7 vertical wedges (sixties place), 4 corner wedges + 6 vertical wedges (units place)
7 × 60 + 46 = 466. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
upsilon, then xi, then stigma, marked as a numeral
upsilon-xi-stigma + keraia
upsilon + xi + stigma 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 samekh, then vav
tav-samekh-vav
tav (400) + samekh (60) + vav (6) = 466, 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.
