Every Wednesday Nibcode Solutions will bring you a new Linear Algebra problem, which answer will be published on Tuesdays following week. Problems will cover the most important Linear Algebra topics, ranging from simple problems to some a little more complex, but all of them aimed to provide examples for you to understand the primary concepts and problem solving methods of Linear Algebra.

This problem of the week involves multiplication of matrices, which is considered the most important matrix operation, and although is not quite as straightforward as addition, the method is not difficult to grasp.
