In historical numeral systems
Egyptian
1 lotus, 3 coils of rope, 8 hobbles, 3 strokes
1 × 1,000 + 3 × 100 + 8 × 10 + 3 × 1 = 1,383. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 3 vertical wedges (sixties place), 3 vertical wedges (units place)
23 × 60 + 3 = 1383. Places are separated by a space on the tablet, with the higher place written first.
