1 × 1,000 + 2 × 100 + 3 × 10 + 8 × 1 = 1,238. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

20 × 60 + 38 = 1238. Places are separated by a space on the tablet, with the higher place written first.

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.
