In historical numeral systems
Egyptian
1 lotus, 1 coil of rope, 9 hobbles, 3 strokes
1 × 1,000 + 1 × 100 + 9 × 10 + 3 × 1 = 1,193. 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), 5 corner wedges + 3 vertical wedges (units place)
19 × 60 + 53 = 1193. Places are separated by a space on the tablet, with the higher place written first.
