Studying Is the suggestion for self-learning mathematics from books wrong?

[user079622]

Why some people suggest self learn math from books, is the suggestion for self-learning mathematics from books wrong?
For example, I think that men how never get in contact with calculus(plus have gaps in prior knowledge), will have really hard time to self learn topic with only books. When you stuck in one part in book, who will ask for help? Book can't talk

If we can just self learn from books, why we have teachers?
I think teacher or any person who will explain the material to you(in person or video lecture) is better option than self learn from book.

What do you think about it?

I think you have the right idea.

While self-teaching is certainly possible, to really establish a solid foundation in just about any STEM topic, it tends to be far more efficient to go through formal instruction from experts. As a learner this gives you formal, standardized, external feedback on your knowledge base and your skill set. It helps you to identify gaps in understanding. It gives you the opportunity to seek assistance when you encounter problems. And when you're done, you have a credential that others will recognize.
