Quick point of feedback: the first two imperative (+=) statements presumably are being treated as independent, not part of the same sequence. I.e.: "20" + 10

Quick point of feedback: the first two imperative (+=) statements presumably are being treated as independent, not part of the same sequence. I.e.: "20" + 10 = "2010" 10 + "20" = 30 This was confusing, given that they are sequential statements listed without any clear separation.
