Welcome to MathMathGood


Our beliefs

What is mathematics?
Is it only just a simple tool for calculating?

In the words of Pythagoras, a Greek mathematician, "Number rules the universe".
Mathematics is everywhere. It can exist in places all around you, and even to the most distant galaxy from our earth. Math is the most important study to learn in order to solve the countless mysteries of the universe. MathMathGood wants to share the importance of mathematics to the people, and discuss how we could achieve a peaceful future society for all of us.

Our beliefs will be abided by the article of association and will be unalterable.
Our goals are to find talented young people with innate mathematical abilities by supporting their environment. MathMathGood looks forward to finding someone brilliant who would save the earth and life that live upon it.

We hope for your help to accomplish our dreams.
