The Indian-Arabic numbers arrived in Iceland in the 14th century;
in the well known Hauksbók manuscript (among other things containing
an important copy of Völuspá) there is a short treatise on them.
The beginning is, quoting from memory, like this.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
List þessi heitir ALGORISMUS. Hana fundu fyrst indverskir menn ok
skipuðu með .x. stöfum þeim er svá eru ritnir:

0 1 2 3 4 5 6 7 8 9
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

The date on the Kensington stone is, quoting from the same memory,
written with some sort of runic decimal symbols. I think they have
recently been defended as not out of place.
