We apply distributivity to applicable expressions, specifically with the following rewrite rules: (x OPL a) OPR (x OPL b) -> x OPL (a OPR b) (y OPR (x OPL a)) OPR (x OPL b) -> y OPR (x OPL (a OPR b)) ((x OPL a) OPR y) OPR (x OPL b) -> (x OPL (a OPR b)) OPR y (x OPL a) OPR ((x OPL b) OPR y) -> (x OPL (a OPR b)) OPR y (x OPL a) OPR (y OPR (x OPL b)) -> (x OPL (a OPR b)) OPR y where a, b are constants.
