Let's start with some shameless self-promotion: this week, Andreea Calude and I published a paper on Indo-European numerals. We investigate how these languages form numerals beyond 1-10, so 11-99, 100s, and 1000s. There are many famous languages around with crazy numeral systems but we were interested in both the regular and the crazy. For that purpose, we investigate data from Eugene Chan's amazing database 'Numeral system's of the world's languages' to get an overview of how regular and how crazy the Indo-European languages are.
