Mathematics, it is a very vast subject. There are many mathematicians who develop different rules and principles to make kinds of stuff very easy to calculate and solve. From our childhood when we start learning from that point till our ending of a life that is in our full lifespan we use mathematics each and everywhere in terms of calculation or in terms logical analysis or any different kind of kinds of stuff if we think on that we can relate. Here, I will not go into that philosophy. I just gave a brief introduction on how mathematics can be a vast area of discussion. I am a mathematics tutor. I help students and needy people who want to solve their problems. This is a platform where students can post their queries, doubts, and questions and get their solution free of cost. This is an initiative from my side to help needy students. Any tutor also can also contribute their work if they want.  Thank you all.
