Where 8880 fits
Why 8880 is special

2 × 4,096 + 2 × 256 + b × 16 + 0 × 1 = 8,880
Read as powers of two: 8,192 + 512 + 128 + 32 + 16 = 8,880.

8 × 1,000 + 8 × 100 + 8 × 10 = 8,880. 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.
