No, they have the same dimensions, but corresponding elements are not equal.

If two matrices have the same number of rows and same number of columns,
then the *matrix sum* can be computed:

If **A** is an MxN matrix, and **B** is also an MxN matrix, then
their sum is an MxN matrix formed by adding corresponding
elements of **A** and **B**.

Here is an example of this:

Of course, in most practical situations the elements of the matrices are real numbers with decimal fractions, not the small integers often used in examples.

What 3x2 matrix could be added to a second 3x2 matrix without changing that second matrix?
