  • I am sorry to see this was downvoted with no explanation, but it seems to me to be identical to backpackcodes’s answer minus some of his remarks, so I suppose it was justified. Commented Jan 8, 2017 at 20:07
  • @PJTraill I must have missed that, it is indeed almost identical. However, I strongly prefer having the operators on the new lines, which is why I'll let my version stand. Commented Jan 8, 2017 at 20:11
  • I agree about the operators, as I remarked in a comment on the other answer — I hadn’t spotted that you had done it as I prefer. Commented Jan 8, 2017 at 20:18
