22 in Roman Numerals
22 is written as XXII in Roman numerals.
How XXII is built
Roman numerals are written one place value at a time, largest first. 22 splits into 20 (tens) + 2 (ones), and each piece becomes its own group of symbols:
| Symbol | Value | Running total | Note |
|---|---|---|---|
| X | 10 | 10 | |
| X | 10 | 20 | |
| I | 1 | 21 | |
| I | 1 | 22 |
Read left to right, the symbols add up: 10 + 10 + 1 + 1 = 22. XXII needs no subtractive pairs: every symbol in it is simply added, because no place value of 22 is a 4 or a 9.
The symbol X (10) is the largest one used to build XXII -- it also shows up in 81 other numbers between 1 and 100.
