XXXVIII
= 38

Step by step breakdown:

1
XXX = 30 (three tens)
2
VIII = 8 (five plus three)
3
XXXVIII = 30 + 8 = 38 (addition of values)
Final result: XXX + VIII = XXXVIII (38)

The notation XXXVIII perfectly illustrates the additive nature of Roman numerals. This number uses only addition, making it straightforward to read and understand: XXX + VIII = XXXVIII.

Arabic number Roman numeral Method
36 XXXVI 30 + 6 = addition only
37 XXXVII 30 + 7 = addition only
38 XXXVIII 30 + 8 = addition only
39 XXXIX 30 + (10 - 1) = addition and subtraction
40 XL 50 - 10 = subtraction only
48 XLVIII (50 - 10) + 8 = subtraction and addition

XXXVIII is the last number in the thirties that uses only addition before the Roman system transitions to subtraction rules.

How to remember the Roman thirty-eight notation?

To easily remember that 38 is written as XXXVIII:

  • Break it down: 38 = 30 + 8
  • XXX represents thirty (three tens)
  • VIII represents eight (five plus three)
  • Remember: XXXVIII uses only addition, no subtraction needed
  • Think of it as "thirty plus eight" in Roman symbols
