Invariant basis number for Rings.
$begingroup$
Let $R$ be a ring with identity. Let $M_{n}(R)$ be the ring of $n$ by $n$ matrices with entries in $R$. Prove that $R$ has IBN iff $M_{n}(R)$ has IBN.
I was given this problem. I thought a little about that and came out with nothing special. So if you could give some hint on that, it would be great.

Have a look on exercises in modules and rings, e.g. here (Exercise $1.14$).
