commutative
의미: Describing a mathematical operation in which the order of the operands does not affect the result, so that a + b equals b + a.
Addition and multiplication of real numbers are commutative, but subtraction, division, and matrix multiplication are not. The commutative property is one of the foundational axioms in algebra and features prominently in ring theory and group theory, where 'commutative' (or 'abelian') groups have special properties. Understanding which operations commute and which do not is essential in abstract algebra, quantum mechanics, and theoretical computer science.
예문
- Addition is commutative because three plus five yields the same result as five plus three. 加法是交换的,因为三加五与五加三得到相同的结果。La suma es conmutativa porque tres más cinco da el mismo resultado que cinco más tres.加法は可換である。なぜなら3足す5は5足す3と同じ結果になるからである。덧셈은 교환법칙이 성립한다. 3 더하기 5는 5 더하기 3과 같은 결과를 내기 때문이다.
- The lecturer emphasised that matrix multiplication is not commutative: AB and BA generally produce different results. 讲师强调矩阵乘法不是交换的:AB和BA通常产生不同的结果。El profesor subrayó que la multiplicación de matrices no es conmutativa: AB y BA generalmente producen resultados diferentes.講師は行列の乗法は可換ではないことを強調した——ABとBAは一般に異なる結果を生じる。강사는 행렬의 곱셈에는 교환법칙이 성립하지 않음을 강조했다——AB와 BA는 일반적으로 다른 결과를 낸다.
- Commutative algebra, the study of commutative rings and their ideals, provides the theoretical foundation for much of modern algebraic geometry. 交换代数——研究交换环及其理想的学科——为现代代数几何的大部分内容提供了理论基础。El álgebra conmutativa, el estudio de los anillos conmutativos y sus ideales, proporciona el fundamento teórico de buena parte de la geometría algebraica moderna.可換代数学——可換環とそのイデアルを研究する分野——は、現代代数幾何学の多くの理論的基盤を提供している。가환대수학——가환환과 그 아이디얼을 연구하는 분야——은 현대 대수기하학의 많은 이론적 기반을 제공한다.

기원과 역사
From Latin commutare (to change altogether, exchange), combining com- (together) and mutare (to change). The mathematical sense was formalised in the 19th century by mathematicians including François Servois.
