73 in Roman Numerals
73 is written as LXXIII in Roman numerals.
How LXXIII is built
Roman numerals are written one place value at a time, largest first. 73 splits into 70 (tens) + 3 (ones), and each piece becomes its own group of symbols:
| Symbol | Value | Running total | Note |
|---|---|---|---|
| L | 50 | 50 | |
| X | 10 | 60 | |
| X | 10 | 70 | |
| I | 1 | 71 | |
| I | 1 | 72 | |
| I | 1 | 73 |
Read left to right, the symbols add up: 50 + 10 + 10 + 1 + 1 + 1 = 73. LXXIII needs no subtractive pairs: every symbol in it is simply added, because no place value of 73 is a 4 or a 9.
The symbol L (50) is the largest one used to build LXXIII -- it also shows up in 49 other numbers between 1 and 100.
