Read as powers of two: 64 + 32 + 8 = 104.
In historical numeral systems
Egyptian
1 coil of rope, 4 strokes
1 × 100 + 4 × 1 = 104. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 vertical wedge (sixties place), 4 corner wedges + 4 vertical wedges (units place)
1 × 60 + 44 = 104. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then delta, marked as a numeral
rho-delta + keraia
rho + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then dalet
qof-dalet
qof (100) + dalet (4) = 104, written in descending order.
Maya
1 bar (upper, twenties place) over 4 dots (lower, units place)
5 × 20 + 4 = 104. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.
