If it is the case that I wish to concentrate my efforts in learning Probability, Statistics and Game Theory, then is it also the case that I must become proficient in calculus?
Is calculus a foundation for all mathematical learning... or are there other foundations that would better pertain to Probability, Statistics or Game Theory.
I ask this because
-When reading books such as "Introduction to Probability" "Introduction to Statistics" or "Introduction to Game Theory" I always end up encountering terminology or notation that I cannot understand and therefore cannot progress through the rest of the book. I am unfamiliar with the terminology/notation and my immediate reaction is that these terminology/notation are related to calculus in some way ---> am I mistaken in this assumption? Are there mathematical foundations outside of calculus?
