Binary

1 0 0 1 1 1 0 0 0

1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 1 × 16 + 1 × 8 + 0 × 4 + 0 × 2 + 0 × 1 = 312

Octal

4 7 0

4 × 64 + 7 × 8 + 0 × 1 = 312

Hexadecimal

1 3 8

1 × 256 + 3 × 16 + 8 × 1 = 312

Read as powers of two: 256 + 32 + 16 + 8 = 312.

In historical numeral systems

Egyptian

3 coils of rope, 1 hobble, 2 strokes

3 × 100 + 1 × 10 + 2 × 1 = 312. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

5 vertical wedges (sixties place), 1 corner wedge + 2 vertical wedges (units place)

5 × 60 + 12 = 312. Places are separated by a space on the tablet, with the higher place written first.

Greek (Ionic)

tau, then iota, then beta, marked as a numeral

tau-iota-beta + keraia

tau + iota + beta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.

Hebrew numerals

shin, then yod, then bet

shin-yod-bet

shin (300) + yod (10) + bet (2) = 312, written in descending order.

Maya

3 bars (upper, twenties place) over 2 bars + 2 dots (lower, units place)

15 × 20 + 12 = 312. 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.
