1 × 1,000 + 5 × 100 + 2 × 10 + 8 × 1 = 1,528. 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), 2 corner wedges + 8 vertical wedges (units place)
25 × 60 + 28 = 1528. Places are separated by a space on the tablet, with the higher place written first.
