Math notation, and there can be several is like a foreign language. You can only to learn it by using it a lot in practice. You can't just read a book that tells you how to speak a foreign language and that would be it. You have to learn and understand the symbols, and then you have to learn and understand what is being said using those symbols. You need to learn the letters and the words made with them and then sentences made out of words. It's a lot to learn. But practice makes perfect.
