what does lx stand for in roman numerals
Roman numerals The numerals for 4 (IIII) and 9 (VIIII) proved problematic (among other things, they are easily confused with III and VIII), and are generally replaced with IV (one less than 5) and IX (one less than 10). This feature of Roman numerals is called subtractive notation.
Medical prescription 'â„ž' is a symbol meaning "recipe". It is sometimes transliterated as "Rx" or just "Rx". This symbol originated in medieval manuscripts as an abbreviation of the Late Latin verb recipe, the second person singular imperative form of recipere, "to take", thus: "take thou".[3] Medieval prescriptions invariably began with the command to "take" certain materials and compound them in specified ways.[4]
