With all the new matrix math operations, I think it's worth combining some into a single node to keep things clean.
This design choice has already been used for the Math, Vector Math and Combine/Separate Color nodes.

This node features the current Multiply, Invert, Transpose operations.
I added new operations Add, Subtract, Scale, Normalize, Determinant and Adjoint.
I haven't removed the old nodes yet, as I wanted to hear your thoughts before doing so.

The "Transform Point", "Transform Direction" and "Project Point" nodes involve matrix math too, but since they have a different use case I don't mind keeping them separate

It was an explicit decision to use separate nodes here. See #109965.

In that case, what is your opinion on Add, Subtract, Scale, Normalize, Determinant and Adjoint?
Are any of them be worth adding as separate nodes?

Thanks. If there is a use case for these nodes it probably makes sense to add them. I wasn't in a rush in order to know more about how people wanted to use the nodes first.
