In this book the authors introduce a new type of product on matrices called the natural product Xn. This is an extension of product carried out in the case or row matrices of the same order.
Further, when two column matrices of same order can be added, nothing prevents one from multiplying them.
This sort of multiplication which is natural is defined as natural product Xn on matrices.
We suggest 100 problems and some of them are at the research level.
