In historical numeral systems
Egyptian
6 coils of rope, 2 strokes
6 × 100 + 2 × 1 = 602. 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 vertical wedges (units place)
10 × 60 + 2 = 602. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
chi, then beta, marked as a numeral
chi-beta + keraia
chi + beta 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 bet
tav-resh-bet
tav (400) + resh (200) + bet (2) = 602, 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.
