16 in Roman Numerals
16 is written as XVI in Roman numerals.
How XVI is built
Roman numerals are written one place value at a time, largest first. 16 splits into 10 (tens) + 6 (ones), and each piece becomes its own group of symbols:
| Symbol | Value | Running total | Note |
|---|---|---|---|
| X | 10 | 10 | |
| V | 5 | 15 | |
| I | 1 | 16 |
Read left to right, the symbols add up: 10 + 5 + 1 = 16. XVI needs no subtractive pairs: every symbol in it is simply added, because no place value of 16 is a 4 or a 9.
The symbol X (10) is the largest one used to build XVI -- it also shows up in 81 other numbers between 1 and 100.
