1 × 1,000 + 6 × 100 + 1 × 10 + 9 × 1 = 1,619. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

26 × 60 + 59 = 1619. Places are separated by a space on the tablet, with the higher place written first.

That framework was assembled through colonial statutes across the following half-century, which makes it a legal construction rather than an inheritance.
