<p>Those are the Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc. to count earlier. When life became complex, a<a>standard form</a>was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), D (100), and M (1000) are the symbols we use to count.</p>
