Practice question · Multiple choice
Matrix multiplication is associative but not commutative. What does each property say about the transformations involved?
Hints
- Rotate this page 90° then flip it. Now do those in the other order.
- Grouping is not the same as ordering.
Show the answer
C. Grouping does not change the result, but ORDER does
Why
Both properties are geometric facts. Associativity is why a chain can be pre-multiplied into one matrix; non-commutativity is why the chain must be kept in order when you do.
