Is it known that the multiplication of matrices is a associative operation ?
So,is the relation $(A \cdot B) \cdot C=A \cdot (B \cdot C)$ true??
($A,B,C$ are matrices)

Yes. This is a well known fact which is proved in any (descent) linear algebra book.
The proof is simple, just calculate both the RHS and the LHS to see both are the same
