Ah right I remember hearing somewhere that you guys don't have words for 70, 80, and 90 and do this odd sum of two thing. I suppose there are worse ways than the reverse German :D
The French language has such words, but Frenchmen don't use them. For example they prefer to say the old fashioned "quatre-vingt-dix" (4 - 20 - 10) instead of the perfectly fine "nonante" that French speakers in Belgium use.
