Getting to Know the Roman Numeral XII:
The Roman numeral 'XII' is a very important symbol for understanding time! It's made of an 'X' (ten) and two 'I's (two ones) standing right after it. In the Roman system, this is a clear code for 'ten and two more', which makes twelve! This is a perfect example of the additive principle. The number twelve is special because it's the final number on a clock face, representing either noon or midnight. Understanding 'XII' helps us connect this ancient counting system to the way we organize our modern lives every single day.
