The associativity of an operator defines the order in which operators of the same precedence are grouped (right-to-left or left-to-right).

操作符的结合性定义了相同优先级操作符组合的顺序(从右至左或从左至右)。

Remember that you may need to consider associativity of the operators in order to determine the answer in the case of expressions involving more than one operator.

记住，你可能需要考虑操作符的结合性，以便在表达式含有多个操作符的情况下确定答案。
