In historical numeral systems
Egyptian
9 coils of rope, 9 hobbles, 2 strokes
9 × 100 + 9 × 10 + 2 × 1 = 992. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 6 vertical wedges (sixties place), 3 corner wedges + 2 vertical wedges (units place)
16 × 60 + 32 = 992. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then koppa, then beta, marked as a numeral
sampi-koppa-beta + keraia
sampi + koppa + beta 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 tsadi, then bet
tav-tav-qof-tsadi-bet
tav (400) + tav (400) + qof (100) + tsadi (90) + bet (2) = 992, 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.
