This paper mainly discuss some property of ring which fit into anti-commutative law, and arrive at a conclusion that anti-commutative law is commutable.───本文主要讨论了适合反交换律的环的一些性质，并得出反交换环一定是交换环。
Heisenberg had not proceeded very far with this idea before he noticed that it would lead to his physical quantities not satisfying the commutative law of multiplication.───意识到矩阵表示将导致物理量不满足乘法交换律之前，海森堡并没有前进太远。
We then can verify the associative law and the commutative law for multiplication, and the uniqueness of the result of addition indicates the uniqueness and the cancellation law for multiplication.───我们容易验证乘法满足结合律和交换律，并且由加法结果的唯一性得出乘法结果的唯一性和乘法消去律。
Generally the arithmetic of the matrix multiplication unconformity commutative law, but under special conditions they are interchangeable.───矩阵的乘法运算一般不满足交换律，但在特殊的条件下可交换。
