1 × 1,000 + 1 × 100 + 7 × 10 + 8 × 1 = 1,178. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 9 vertical wedges (sixties place), 3 corner wedges + 8 vertical wedges (units place)
19 × 60 + 38 = 1178. Places are separated by a space on the tablet, with the higher place written first.
