User:Zahlendreher

Hi! You might want to know what my user name Zahlendreher means. It refers to a digit transposition, which is more likely in several languages, like my mother tongue German, as some numbers are pronounced in reversed order, like 21: Einundzwanzig (word by word translation one and twenty). Apart from mathematical topics I mainly contribute to the local history of my home town Berlin. Please excuse if, as a non-native speaker, the language in my contributions is far from being perfect.
