    I found a few other sites out there that are writing about Scala and Project Euler:
    Dianne Marsh’s Blog
    Memetic Musings
    Blok Blogs

    How does this filter out the multiples of 15? Does FoldLeft remove duplicates?

    (1 until 1000).filter(n => n % 3 == 0 || n % 5 == 0).foldLeft(0)(_ + _)

    @Jim H In that case we don’t need to subtract the multiples of 15 because they aren’t counted twice like they were in the first example. When foldLeft operates on the range, there is only one instance of 15 in the range.

    Scala seems like messy Python. I probably need to look into it more though
