The ancient Romans developed a terrible numbering system in which I, V, X, L and C stood for 1, 5, 10, 50 and 100, respectively. So XXXVII represents 37 (10+10+10+5+1+1). They typically wrote the numerals in non-increasing order. However, when a single Roman numeral is written before one that is larger, we subtract the smaller from the larger. So we can write IV and IX to represent 4 and 9 (subtracting 1), or XL and XC to represent 40 and 90 (subtracting 10). To represent 94, we would write XCIV. VIC is generally not considered a traditional Roman numeral, but we can interpret this as another representation of 94: VI is 6, so VIC is 100-6. In general, if we have two expressions a and b representing values v(a) and v(b), then we say that v(ab) is v(a) + v(b) if v(a) v(b), and v(b)
