hello everyone i'm revising the entire high school mathematics as a prerequisite for learning discrete mathematics so i'm having slight confusion in the following topics
(1):What does equivalence class refers to and explain with an example?
(2):  how to prove a function whether its a surjective mathematically?

I think worst way to learn mathematics is not developing encouraging mindset within students or learners  which results in hatred/dislike of the subject what do i believe is that math is like a language in which one could build things by using ,understanding the systems using it.Im currently pursuing bachelors in statistics and mathematics , there are many mistakes that i've commited while learning mathematics and best way to learn mathematics is through understanding and observing the mistakes.

Yes now I'm studying statistics and mathematics at university and in free time i write funny programs on  r.
R is  open source statistical software which is beneficial for data analysis. But thinking about research in mathematical statistics.

Hey 666 bro,
I'd recommend the book Statistical Inference(ISBN-13:978-0534243128) by George Casella and Roger L. Berger. Statistics is quite the varied field and there's not one generally accepted view on how to approach it. But the book Statistical Inference is comprehensive, robust, and remarkably understandable.

thanks Mathegocart i'll have a look on that book.

while learning about normal distribution in probability theory
i came across standard normal distribution and my questions are:
(1): why do we use standard normal distribution?
(2): real world applications of normal disrtibution?
(3): difference between z score and standard normal distribution?
