In historical numeral systems
Egyptian
6 coils of rope, 2 hobbles, 7 strokes
6 × 100 + 2 × 10 + 7 × 1 = 627. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge (sixties place), 2 corner wedges + 7 vertical wedges (units place)
10 × 60 + 27 = 627. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
chi, then kappa, then zeta, marked as a numeral
chi-kappa-zeta + keraia
chi + 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
tav, then resh, then kaf, then zayin
tav-resh-kaf-zayin
tav (400) + resh (200) + kaf (20) + zayin (7) = 627, 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.
