交换律
1.
The commutative law holds for superposition without exception,but it does not necessarily for accumulation.
叠加必然满足交换律,累加则不一定满足交换律。
2.
The note gives some examples on a set with two binary operations which satisfying, or unsatisfying, respectively, the commutative law, the associative law and the distributive law; and discusses the examples satisfying n -element distributive law but not satisfying (n-1) -element distributive law.
给出一个集合上的两个 (二元 )代数运算分别满足或不满足交换律、结合律和分配律的各类例子 ,同时给出了n元分配律成立而 n-1元分配律不成立的例子 。
