How to study math analysis?

Question

Mathematics

Good afternoon. I wanted to read a book about algorithms (T. Kormen - Algorithms. Construction and Analysis) , but, having looked through, I saw a lot of mathematical expressions and functions that I did not understand (like the logarithm or that thing in the attached screenshot) .
What sections of mathematics should I learn and from what books? (I prefer textbooks, not video courses)
PS: I'm in the 10th grade, I have some ideas about limits and derivatives.

Answer 1

Linear algebra and mat. analysis in the volume of 1 course of St. Petersburg State University or Moscow State University. This is enough for the eyes for 95% of algorithms.
In general, if you are in the 10th grade, just study the program ahead.
