<p>Earlier people used to count using fingers, sticks, bones, etc. to count earlier. When life became complex, a standardized form was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.</p>
