In historical numeral systems
Egyptian
1 lotus, 2 coils of rope, 2 hobbles, 4 strokes
1 × 1,000 + 2 × 100 + 2 × 10 + 4 × 1 = 1,224. 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), 2 corner wedges + 4 vertical wedges (units place)
20 × 60 + 24 = 1224. Places are separated by a space on the tablet, with the higher place written first.
