Where 943 fits
Why 943 is special
It generalises SQL injection to every query language, which matters now that so many applications query document stores and directories instead.

Roman numerals
C M X L I I I
CMXLIII uses the subtractive pair XL: ten before fifty — fifty minus ten.
Binary
1 1 1 0 1 0 1 1 1 1
1 × 512 + 1 × 256 + 1 × 128 + 0 × 64 + 1 × 32 + 0 × 16 + 1 × 8 + 1 × 4 + 1 × 2 + 1 × 1 = 943
Octal
1 6 5 7
1 × 512 + 6 × 64 + 5 × 8 + 7 × 1 = 943
Hexadecimal
3 a f
3 × 256 + a × 16 + f × 1 = 943
Read as powers of two: 512 + 256 + 128 + 32 + 8 + 4 + 2 + 1 = 943.
In historical numeral systems
Egyptian
9 coils of rope, 4 hobbles, 3 strokes
9 × 100 + 4 × 10 + 3 × 1 = 943. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 5 vertical wedges (sixties place), 4 corner wedges + 3 vertical wedges (units place)
15 × 60 + 43 = 943. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then mu, then gamma, marked as a numeral
sampi-mu-gamma + keraia
sampi + mu + gamma 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 mem, then gimel
tav-tav-qof-mem-gimel
tav (400) + tav (400) + qof (100) + mem (40) + gimel (3) = 943, 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.

Common questions
Is 943 a prime number?
No, 943 is not prime.
What are the factors of 943?
The factors of 943 are 1, 23, 41, 943.
What is 943 in Roman numerals?
943 in Roman numerals is CMXLIII. XL is subtractive: ten before fifty — fifty minus ten. Written additively it would be DCCCCXXXXIII, which Roman inscriptions used freely — the strict subtractive form is a later convention.
