"WebThe above BNF grammar forces the left addition of the statement A=B+C+A to be lower in its parse tree, hence it will be evaluated ﬁrst, because addition is left associative. While the right exponentiation of the statement A=B^C^A is lower in its parse tree, hence it will be evaluated ﬁrst, because exponentiation is right associative. 6 " - Right associative bnf
