# 70 in Roman numerals

**70 in Roman numerals: LXX**

70 is written LXX in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*LXX = 50 + 10 + 10 = 70*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| L | 50 | — | 50 |
| X | 10 | — | 60 |
| X | 10 | — | 70 |

## No subtraction needed

LXX is purely additive — every symbol is simply added to the one before it, with no subtractive pairs like IV or IX. Numbers avoid subtraction when none of their digits is a 4 or a 9.

## The symbols
