The to_s method is going to be called on whatever value the #{ ... }
evaluates to.  That's why you are getting "ab"

    a.each {|i| i * b}.to_s # => "ab"

if you use collect rather than each, you'll get

    x = a.collect {|i| i * b}  # => ["aa", "bb"]
    x.to_s                        # => "aabb"
