Roman Numerals


Roman numerals are written using the seven letters of the alphabet (shown in Table)

There are certain rules when using Roman numerals:
Letters are arranged from the largest to smallest.
Numbers are added to arrive at the value.
  • For example XVI is X (10) +V (5) + I (1) = 16.

When a smaller number precede a larger number, the smaller is subtracted from the larger.
  • For example: IX is 1 (I) subtracted from 10 (X) = 9.
