1 × 1,000 + 3 × 100 + 4 × 10 + 3 × 1 = 1,343. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 2 vertical wedges (sixties place), 2 corner wedges + 3 vertical wedges (units place)
22 × 60 + 23 = 1343. Places are separated by a space on the tablet, with the higher place written first.
