I want to explain a topic that will help in solving mathematical problems. It will help in becomes little faster than as compared with your classmates in your class. Today I'll select the topic matrices. In matrices, I am willing to explain how to find A^-¹ which is the toughest part of the matrices chapter I think and the remaining topics inconsistent and consistent are. Also a little bit tough but finding A^-¹ is a little bit late to calculate. And I will explain how the answer that I got was correct through a simple process it makes takes upto 5-6 minutes to explain. And in case if you are interested in learning some more then I will take another topic that was tough for you to learn from the class. I am very excited to start a regular class with you through this.
