В 1714 г. Петр I издал указ об обязательном обучении дворянских детей «цыфири и геометрии»

In order to draw greenhorns out of darkness of ignorance, the decree ordered to “send several graduates of mathematics schools to all provinces.” Being well aware of the customs in his motherland, the Tsar knew that punishment should be set for non-compliance. He invented a penalty for sexually mature greenhorns. Marriage was forbidden for those who failed to learn the Pythagorean theorem, as well as rules of addition, subtraction, multiplication and division. Thus, those craving for getting married had to get to know the terrible beasts of sciences against their will. Today, every third-form pupil knows these rules which are just the four arithmetic operations.
