The maximum times a Roman numeral can appear in succession is three. I is one, II is two and III is three. To make four, however, you must subtract one from five. When a number is subtracted, it appears to the left of the number from which it is taken. For example, four is IV.
Six is written as five plus one. When a number is added to another, it appears to the right of it. By this rule, six is VI, seven is VII and eight is VIII. Nine is written as 10 minus one, or IX.
Twenty is XX, and 30 is XXX. Forty is written as 50 minus 10, or XL. Similarly, 90 is 100 minus 10, or XC.
