mathematics is not some mystical kungfu

I guess you haven't been initiated yet.
No, seriously, I also like Vellemans book more. It's true that it has more emphasis on set theory, but this is in fact a very good thing. Many people find mathematics difficult because they don't understand set theory well, so the faster you'll be introduced to set theory and the likes, the better for you.
Also, I found "100% mathematical proof" too chaotic. And a lot of the book is concerned with stuff you'll never need again...
