> How can a self-learner without access to a university or professor check their work? Their "work" means: Find a solution, AND then check it. So, not checking it by yourself is being lazy too. Also, if you are learning; software like wolframalpha can help you too to check your solution. [Thanks, throwawaymath for recall this basic answer]. > I wouldn't want a beginner programmer writing "production ready" code without code review, so why should we expect a beginner math student to write error free proofs? "Code Reviews" are for checking "how did the programmer solved that problem". On the other side; you know if some code is giving good or bad outputs by checking it with "Tests" (In the worst scenario; manually). So, you have to learn to "test" your solution. The creativity is in how you managed to get the solution and teachers should give insights about your way to solve it and present you easier or better ways to achieve the same. (Just change "teachers" for "senior devs" and now, that is code review). > These text seem to be designed solely for a classroom where students will get assistance and feedback from TAs and professors. Probably that's true. You have to consider those types of books as "slides"; just like a guide for the teacher and memory refresh for students.
