A sign-value notation is a numeral system in which the number or value represented by each symbol or sign does not depend on their position in a sequence. Sequential signs are typically combined in an additive, subtractive, or multiplicative manner to represent larger values by convention. Although the absolute value of each sign is independent of its position, the value of the resulting sequence as a whole may depend on the order of the signs. This is the case with numeral systems which combine additive and subtractive notation, such as Roman numerals. There is no need for zero in sign-value notation.
