Pay attention in class, study, and do your homework. There is no fast solution.
Do lots and lots and lots of examples so you don't have to think twice about how to solve simultaneous equations or whatever the problem is. Practice practice practice practice
Also try to UNDERSTAND what is going on. If you memorize formulas, you will soon forget them. If you understand you will remember and be able to generalize.
Ask questions, look things up, do whatever you need to gain intuition about the math.
DO NOT just blindly memorize it.
The only way to get good at math fast is to practice.

I'm assuming that you mean get used to math so you can do it fast. This may or may not be an easy goal for you but the only answer is Practice.
A pattern is like an a b pattern in math
The logical inverse of (if A then B) is (if not B then not A).
