Welcoem to posts!!
in the future - u will be able to do some more stuff here,,,!! like pat catgirl- i mean um yeah... for now u can only see others's posts :c

Welcome to my new channel.
We will be exploring mathematical problems that arise in all different fields of mathematics. We will focus on simpler and familiar ones.
The aim of this channel is to help the students looking for detailed and well explained solution . To achieve this aim we have set a strategy that is based on your interaction with us. Simply, we mean that students will have to interact with the videos.
The topics covered here will require some effort of your behalf .
We have tremendous expertise that we accumulated during many years of work. Different backgrounds will be involved and that means different ways of solving the problems will be shown.
We will focus on solving every problems that we post. We will delay the solution a bit to encourage to find the solutions by yourself.
Note that the approach that we used in the early videos is based on face to face experience or tutor student approach.
We will cover simple problems to more advanced problems.
Welcome
