Examples of Vigesimal Systems
Welsh
The Welsh language shows the remnants of a vigesimal system in its names for certain numbers:
| \(\ds \) | \(20\) | \(\ds \) | ugain | |||||||||||
| \(\ds \) | \(30\) | \(\ds \) | deg ar ugain | \(\quad\) literally: ten and twenty | ||||||||||
| \(\ds \) | \(40\) | \(\ds \) | deugain | \(\quad\) literally: two twenties |
and so on.
