25 in Roman Numerals
25 is written as XXV in Roman numerals.
How XXV is built
Roman numerals are written one place value at a time, largest first. 25 splits into 20 (tens) + 5 (ones), and each piece becomes its own group of symbols:
| Symbol | Value | Running total | Note |
|---|---|---|---|
| X | 10 | 10 | |
| X | 10 | 20 | |
| V | 5 | 25 |
Read left to right, the symbols add up: 10 + 10 + 5 = 25. XXV needs no subtractive pairs: every symbol in it is simply added, because no place value of 25 is a 4 or a 9.
The symbol X (10) is the largest one used to build XXV -- it also shows up in 81 other numbers between 1 and 100.
