1 × 1,000 + 5 × 100 + 5 × 10 + 9 × 1 = 1,559. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 5 vertical wedges (sixties place), 5 corner wedges + 9 vertical wedges (units place)
25 × 60 + 59 = 1559. Places are separated by a space on the tablet, with the higher place written first.
