Egyptian
1 lotus, 2 coils of rope, 3 hobbles, 2 strokes
1 × 1,000 + 2 × 100 + 3 × 10 + 2 × 1 = 1,232. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges (sixties place), 3 corner wedges + 2 vertical wedges (units place)
20 × 60 + 32 = 1232. Places are separated by a space on the tablet, with the higher place written first.
