A scalar, which is a tensor of rank 0, is just a number, e.g. 6
A vector, which is a tensor of rank 1, is a group of scalars, e.g. [1, 6, 3]
A matrix, which is a tensor of rank 2, is a group of vectors, e.g.
1 6 3
9 4 2
0 1 3
A tensor of rank 3 would be a group of matrix and would look like a 3d matrix.
A tensor is the general term for all of these, and the generalization into high dimensions.

actually MATRICES is the plural of matrix which means the array of numbers in groups and columns in a rectangular table... and determinant is used to calculate the magnitude of a matrix....
The matrices must have the same dimensions.
Only square matrices have a determinant
I do not. I f*cking hate matrices. I multiply sheep.
There are no matrices in the question!
