In historical numeral systems
Egyptian
1 lotus, 2 coils of rope, 9 hobbles, 3 strokes
1 × 1,000 + 2 × 100 + 9 × 10 + 3 × 1 = 1,293. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 1 vertical wedge (sixties place), 3 corner wedges + 3 vertical wedges (units place)
21 × 60 + 33 = 1293. Places are separated by a space on the tablet, with the higher place written first.
