1 × 4,096 + 1 × 256 + 9 × 16 + f × 1 = 4,511

Read as powers of two: 4,096 + 256 + 128 + 16 + 8 + 4 + 2 + 1 = 4,511.

In historical numeral systems

4 × 1,000 + 5 × 100 + 1 × 10 + 1 × 1 = 4,511. 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.
