To multiply two matrices,

We first write their order

For multiplication

Since 2 ≠ 3

We cannot multiply them

But, if we multiply BA

Then,

So, order of matrix after multiplication is

=
**
3 × 2
**

Let’s learn how to multiply them

So,

AB was not possible, but BA was possible

Thus, AB ≠ BA

Let’s do some more examples

So, multiplication is not possible
