Frequently asked questions

When can matrices be added?

Only matrices with identical dimensions can be added or subtracted, since the operation is entrywise.

How is matrix subtraction defined?

A − B subtracts each entry of B from the matching entry of A.

Is matrix addition commutative?

Yes. Unlike multiplication, A + B always equals B + A.
