The Mathematics.
First of all, I don’t teach you about some math’s theory, but I’ll speak about interesting things relative to math.
Everybody knows The Math is everywhere therefore into others sciences. For example Physics, Chemistry, Biology, Astronomy, among others. It doesn’t needs other sciences to explain it because explain itself.
Contrary to popular belief the math isn’t numbers science but is structure science that means mathematicians don’t worry to work out, but with other questions for example: Why math’s operations work. Besides, solutions of theoretical problems and new discovers.
The mathematician can understand others fields of study without knows theory about this field.
Only analyzing math expressions, statistician behaviors because many studies in several fields use math to describe them.
Anyway, now a famous quote about math.
“Mathematics is the alphabet with which God has written the Universe”
Galileo Galilei.
That’s all folks.

Thanks by attention.
