As some of you may know, France uses a vigesimal system for numbers. That is, a base-20 system instead of a base-10 system like we normal people use.
Apparently, it's a hard concept even for them. I got this discount check in the mail today from a popular catalog company.
The written amount says "sixty-four," not "seventy-four," which would be "soixante-quatorze" or literally in English, "sixty-fourteen."
My French friend tells me it's the amount spelled out in words that takes precedence, so I guess it's not such a great deal as they'd like to make me think!
