/sci/ - Science & Math

Any maths book I take up to try and study from it goes from 1 to 100 in about 3 and a half pages.

I find I can only do maths if shown by example, like Khan academy or some Youtube videos. No, I'm not a fucking math major and will never be. I don't want to. But what these authors are trying to convey is impossible to understand for someone just beginning to study maths. ANY maths books is fucking riddled with alienspeak moonrune looking notation that probably even people studying math will struggle at first to understand.

The point I'm getting at is, how do you learn to read this notation, in order to be able to actually study high level math? OR any math in general?

Example: "One possible requirement, which is technically rather simple and which
we will use, is:
• There exists a positive number A and an open interval (a, b) which contains t0, such that
|P(t) − L(t)| ≤ A(t − t0)^2 for all t in (a, b)."

Like, what the fuck does this even mean? What is it trying to convey? I simply don't understand why this has anything to do with calculus. This is literally from the 3rd page of this PDF http://www.math.hawaii.edu/~heiner/calculus.pdf
