We show the structure theorem of the monoidal absolute derivations of the matrix algebra over a commutative ring. In particular, those over the ring of rational integers are inner.

We show the structure theorem of the monoidal absolute derivations of the matrix algebra over a commutative ring. In particular, those over the ring of rational integers are inner.
