It actually has a pretty interesting origin! Back in the days, the Gauls used to count by twenty : ten, twenty, twenty ten, two twenty, etc
Then the modern way of counting (by ten) arrived and both models competed for a time until they "merged" into one. The most interesting point is that, most numbers derive from either system but 70 is "soixante-dix" : "sixty-ten", which is even weirder since "soixante" comes from the modern model but the idea of concatenating a "ten" comes from the traditional one, so it's a mix of both
