In historical numeral systems
Egyptian
5 coils of rope, 6 hobbles, 6 strokes
5 × 100 + 6 × 10 + 6 × 1 = 566. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
9 vertical wedges (sixties place), 2 corner wedges + 6 vertical wedges (units place)
9 × 60 + 26 = 566. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
phi, then xi, then stigma, marked as a numeral
phi-xi-stigma + keraia
phi + 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 qof, then samekh, then vav
tav-qof-samekh-vav
tav (400) + qof (100) + samekh (60) + vav (6) = 566, 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.
