How Roman Numerals Work The Rules You Need to Know

Roman numerals use letters to represent numbers, but they follow some basic rules so you don’t get lost:

• When a smaller numeral comes after a bigger or equal numeral, you add it.
  Like VI means 5 + 1 = 6.
  
• When a smaller numeral comes before a bigger numeral, you subtract it.
  Like IV means 5 – 1 = 4.
  
• You never repeat the same letter more than three times in a row.
  So for 4, you don’t write IIII — you write IV.
  
• Some special pairs to know where subtraction happens:
  
  • IV (4), IX (9)
    
  • XL (40), XC (90)
    
  • CD (400), CM (900)

   Write down X.
   
2. Subtract 10 from 27 — now you have 17 left.
   
3. Again, 10 fits into 17, so write another X.
   
4. Subtract 10 from 17 — you have 7 left.
   
5. The largest numeral less than or equal to 7 is V (5). Write V.
   
6. Subtract 5 from 7 — you have 2 left.

For 2, use II (1 + 1).So, 27 in Roman numerals is XXVII
