In historical numeral systems
Egyptian
1 lotus, 9 hobbles, 2 strokes
1 × 1,000 + 9 × 10 + 2 × 1 = 1,092. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 8 vertical wedges (sixties place), 1 corner wedge + 2 vertical wedges (units place)
18 × 60 + 12 = 1092. Places are separated by a space on the tablet, with the higher place written first.
