How to read all the symbols in high numbers and their corresponding meanings?
I'm a single mother. For my baby, I want to continue to study. Recently, I'm studying advanced mathematics by myself to prepare for the exam. There are many symbols in the book that I don't know how to read and it's hard to remember. I hope someone will tell me which knowledge point each symbol appears in,
Some can't even type because they can't read... So they can't check

There are many symbols. I can't write them completely
You can search the Internet for symbols,
What knowledge points appear in this book can be roughly known,
But the meaning of symbols, this is more cumbersome to explain
