Below was the problem statement

In the solution for Z value it is mentioned as

```
matrix1 = np.random.rand(10,20)
matrix2 = np.random.rand(20,30)
z = np.dot(matrix1 , matrix2 )
```

here the sigma n is not considered which is summation of all the values from 1 to n. Is it because n is not esed in the product .
