undefine

#### Explanation:

The product of matrices only can be define when the number of columns in the first matric is equals to the number of rows in the second matric.

for example

Matric M1 has 3 columns and M2 has 3 rows. Then it can be defined

therefore for

You just cannot multiply a

#### Explanation:

You just cannot multiply a

You can only two matrices if number of columns of the first matrix is equal to number of rows of the second matrix.

i.e. you can only multiply a

This is an important part of the process of multiplication.

Let us have a

The result is a

where

If number of columns of the first matrix are not equal to number of rows of the second matrix, which is so in the case mentioned by you, this is not possible and hence, you cannot multiply a

and you can say multiplication of such matrices is not defined.
