In historical numeral systems
Egyptian
4 coils of rope, 5 hobbles, 4 strokes
4 × 100 + 5 × 10 + 4 × 1 = 454. 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), 3 corner wedges + 4 vertical wedges (units place)
7 × 60 + 34 = 454. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
upsilon, then nu, then delta, marked as a numeral
upsilon-nu-delta + keraia
upsilon + nu + delta 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 nun, then dalet
tav-nun-dalet
tav (400) + nun (50) + dalet (4) = 454, 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.
