<p>Royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed these names and wondered what the<a>symbols</a>(I and II) represented? Those are Roman Numerals. Earlier people used fingers, sticks, bones, etc., to count. As life became complex, a<a>standard form</a>was needed for counting. Ancient Romans used the Roman Numeral system. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used to count.</p>
