In historical numeral systems

Egyptian

7 lotuses, 1 stroke

7 × 1,000 + 1 × 1 = 7,001. 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.
