Evolving Technologies

A bird can fly better than human, but an airplain made by human can fly faster and higher than a bird. Samely, an owl can see in the dark via infrared light, but a camera or scope manufactured by human can not only see in the dark, but also in the micro and macro world.

A teacher can teach math, but very near the future, program written by human will be able to teach math more efficiently to students or learners.

So "What is Teaching?".
Teaching is a counter part of learning. The subject is not teaching but learning at inside of a student, especially in brain, widely in a body of human being. There would be no need for a teacher to learn math, but a guide for students to go forward is required.  It is a student or learner that acquires the knowledge and technique of Math.  Sometimes, a teacher can guide stuedents forward the math road, but the same time, many many students in the same class hate math.

Now I would like to introduce the Math App for android. These Apps are for calcuration, linear equation and function, geometry and differentiation, respectively.
