MMXLVI uses the subtractive pair XL: ten before fifty — fifty minus ten.

Read as powers of two: 1,024 + 512 + 256 + 128 + 64 + 32 + 16 + 8 + 4 + 2 = 2,046.
In historical numeral systems
Egyptian
2 lotuses, 4 hobbles, 6 strokes
2 × 1,000 + 4 × 10 + 6 × 1 = 2,046. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 4 vertical wedges (sixties place), 6 vertical wedges (units place)
34 × 60 + 6 = 2046. Places are separated by a space on the tablet, with the higher place written first.
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.

What is 2046 in Roman numerals?
