    q)10*11+3
    140
    q)10*(11+3)
    140

    What is the order of precedence for the various operators in q?
    The answer above is different than in any other language I know.

    q code is has no order of precedence, it is interpreted from right to left. e.g.

    q)3%2-100+10*neg 11+3
    0.07142857
    q)3 % (2- (100+ (10*(neg (11+3)))))
    0.07142857
