Where 8485 fits
Why 8485 is special
Its summit is a near-perfect four-sided pyramid, and the final pitch is technical rock and ice rather than a walk — unusual among the eight-thousanders, most of which end in snow slopes.

8 × 1,000 + 4 × 100 + 8 × 10 + 5 × 1 = 8,485. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
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.
