I am trying to do some simple math in my model, but for some reason, it chokes on division, or at least when I use the \ symbol. I have tried many different iterations, and all math works and loops great til I try to divide two numbers. Am I using the wrong symbol here?

def up

n = up_votes

x = up_votes + down_votes + neutral_votes

y = x/n * 100

return y

end

def down

return ((up_votes + down_votes + neutral_votes)/down_votes ) * 100

end
