Commutatitivity does not need to always hold. Multiplication is not commutative on matrices, but we still use it often and write it as a product nonetheless

- whatshisface 8y agoPython actually supports a special operator @ for non-commutative matrix products.
- Koshkin 8y agoIn mathematics, the ‘multiplication’ operation is not assumed to be commutative, whereas the ‘addition’ operator is used specifically to indicate commutativity. So, for example, using the plus sign for string concatenation goes against this tradition.
