CIV uses the subtractive pair IV: one before five — five minus one.

Binary

1 1 0 1 0 0 0

1 × 64 + 1 × 32 + 0 × 16 + 1 × 8 + 0 × 4 + 0 × 2 + 0 × 1 = 104

Octal

1 × 64 + 5 × 8 + 0 × 1 = 104

Hexadecimal

6 × 16 + 8 × 1 = 104

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.
