High Level Math

When we talk about math, what do you thinking of? Maybe it's so hard to you.

But I'm gonna say, it's not. Actually, it's a fantastic subject you can master.

Every time you think you can't master it is just because of you can't understand it correctly.

Don't worry, I'll help you.

  1. Never give up finding another solution for math problems.

  2. Put math into reality, which is physical and programming.
