ickekommutativitet
Icke-kommutativitet, also known as non-commutativity, is a property of certain mathematical operations where changing the order of the operands affects the result. This concept is most commonly encountered in the context of multiplication of numbers, matrices, and other algebraic structures.
In the realm of numbers, multiplication is generally commutative, meaning that for any two numbers a and
The lack of commutativity in matrix multiplication arises because matrix multiplication is defined in terms of
Non-commutativity is also a key feature of other algebraic structures, such as groups and rings, where the
