Hi Ruby Student,

In that case, use `include` instead of `require` like this:

# test.rb
include Math

class MyClass
  def initialize; end
  def aMethod; end
  v = 125
  alert sqrt(v)
end

Shoes.app :title => "My Title", :resizable => false do
  flow :width => "100%", :margin => 6 do
    stack :width => "30%" do
      para sqrt(144)
    end
  end
  stack :width => "70%" do
    #   blah blah blah
  end
end

Hope this helps,
