In historical numeral systems
Egyptian
9 coils of rope, 1 stroke
9 × 100 + 1 × 1 = 901. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 5 vertical wedges (sixties place), 1 vertical wedge (units place)
15 × 60 + 1 = 901. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then alpha, marked as a numeral
sampi-alpha + keraia
sampi + alpha written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then tav, then qof, then alef
tav-tav-qof-alef
tav (400) + tav (400) + qof (100) + alef (1) = 901, written in descending order.
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.
