Jeden za osmnáct a druhý bez dvou za dvacet aneb záporné cifry v zápisu čísel. (Czech). Rozhledy matematicko-fyzikální, vol. 85 (2010), issue 4, pp. 3-11
Summary:
Most of us use the decimal system with digits 0 to 9 to represent integer numbers. It is technically convenient for computers to represent numbers in the binary system with digits 0 and 1. Although these two number representations are the most common, there are many others, which are often more useful. We shall explore number systems which accept also negative digits.
