Mathematics- just someone use some "reasonable" materials to let people trust what the wordls it is.

I am curious to know how people prove 1+1=2 Sometimes, itis definition of the equation, but not the art of reasoning...

In my mind, Mathematics are the figures that show the common directions of ideas, thoughts, to achieve the harmony on the earth.

We need mathematics, but somehow, I do not understand the nature of Mathematics of 1, 2, 3, 4,5, 6,7,8,9,0.......

What's more, Mthematics gives me paradox of what "truth" existing in our earth. I wish I could find Absloute truth in earth, but still, it's ideal....

Mathematics is only a tool, not a truth
