1 × 1,000 + 8 × 10 + 3 × 1 = 1,083. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 8 vertical wedges (sixties place), 3 vertical wedges (units place)
18 × 60 + 3 = 1083. Places are separated by a space on the tablet, with the higher place written first.
