1 × 1,000 + 3 × 100 + 4 × 10 + 2 × 1 = 1,342. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian

22 × 60 + 22 = 1342. 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.
