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.
Pax Romana The Pax Romana (Latin for "Roman Peace") was a long period of relative peace and minimal expansion experienced by the Roman Empire between the end of the Final War of the Roman Republic and the beginning of the Crisis of the Third Century, a span of roughly two hundred years. During this period, the Roman empire achieved its greatest territorial extent, and its population reached a maximum of up to 70 million people.[1] Since it was inaugurated by Augustus, it is sometimes called the Pax Augusta. Its span was approximately 206 years (27 BC to AD 180), from the accession of Augustus to the death of Marcus Aurelius.[2]
