Roman numerals
C M L X X I
CMLXXI uses the subtractive pair CM: a hundred before a thousand — a thousand minus a hundred.
Binary
1 1 1 1 0 0 1 0 1 1
1 × 512 + 1 × 256 + 1 × 128 + 1 × 64 + 0 × 32 + 0 × 16 + 1 × 8 + 0 × 4 + 1 × 2 + 1 × 1 = 971
Octal
1 7 1 3
1 × 512 + 7 × 64 + 1 × 8 + 3 × 1 = 971
Hexadecimal
3 c b
3 × 256 + c × 16 + b × 1 = 971
Read as powers of two: 512 + 256 + 128 + 64 + 8 + 2 + 1 = 971.
In historical numeral systems
Egyptian
9 coils of rope, 7 hobbles, 1 stroke
9 × 100 + 7 × 10 + 1 × 1 = 971. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 6 vertical wedges (sixties place), 1 corner wedge + 1 vertical wedge (units place)
16 × 60 + 11 = 971. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then omicron, then alpha, marked as a numeral
sampi-omicron-alpha + keraia
sampi + omicron + alpha 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 tav, then qof, then ayin, then alef
tav-tav-qof-ayin-alef
tav (400) + tav (400) + qof (100) + ayin (70) + alef (1) = 971, 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.
