Roman Arithmetic
by G R Burgin
In mathematics, ‘Roman Arithmetic’ is the use of arithmetical operations on ‘Roman Numerals’. Roman numerals are a numeral system of ancient Rome based on letters of the alphabet, which are combined to signify the sum or difference of their values. The Romans depicted numbers using seven letters of the alphabet as numerals: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 & M = 1000. The Roman numeral system does not include a zero and is shown from 1 to 10 as: I, II, III, IV, V, VI, VII, VIII, IX & X.
