In historical numeral systems
Egyptian
1 lotus, 8 hobbles, 6 strokes
1 × 1,000 + 8 × 10 + 6 × 1 = 1,086. 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), 6 vertical wedges (units place)
18 × 60 + 6 = 1086. Places are separated by a space on the tablet, with the higher place written first.
