1 × 1,000 + 6 × 100 + 2 × 10 + 9 × 1 = 1,629. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 7 vertical wedges (sixties place), 9 vertical wedges (units place)
27 × 60 + 9 = 1629. Places are separated by a space on the tablet, with the higher place written first.
