The number system now in commonest use worldwide is positional. Consider a number such as 924.37. The position of each digit in the number indicates how significant it is. The digit 9 represents 100s, the 2 10s, the 4 1s, and so on.
The Roman number, or 'numeral' system, is non-positional. The value of a character in a number does not depend on its position only. Rather, the value of a character depends on what the character is and on neighbouring characters. Consider a number such as XLIV. In this case the 'X' means ten but only as a modifier for the 'L' which stands for fifty, so that the combination 'XL' means 40.
