Roman Numerals- The Rules

When a smaller numeral such as I or X placed after a larger (or equal) one has the effect of added(plus)

  • Example: VII = V + I + I = 5 + 1 + 1 = 7
  • Example: LXXX = L + X + X + X = 50 + 10 + 10 +10 = 80

But a smaller numeral such as I or X placed before a larger one has the effect of subtracted(minus)

  • Example: IV = V − I = 5 − 1 = 4
  • Example: XIX = X − I + X = 10 − 1 + 10 = 19

Roman Numbers 1 to 100

Tips of chart usage:

  • Write numerals left to right, with the largest numeral first.
  • The largest numeral possible is used at each stage.
  • No more than three instances of same adjacent numeral. Occasionally number 4 is written not as IV but as IIII to add symmetry and balance to a watch or clock face.

Here are list of Roman numerals or numbers from 1 to 100.

Remember: I=1, V=5, X=10, L=50, C=100
