Numbers in Proto-Brythonic

How to count in Proto-Brythonic, the reconstructed ancestor of the Brythonic branch of the Insular Celtic languages (Welsh, Cornish, Breton and Cumbric). It is also known as Common Brittonic, and was spoken from about the 6th century BC to the 6th century AD in most of Great Britain south of the Firth of Forth.
