How do I study the books that don't have answers at the back?

Question

There are several classical books on mathematics which are a pleasure to study from. However, after reading its materials and working through the theorems and solved problems, I feel very uncomfortable while solving questions given at the back of the chapter. This happens when they don't have any answers (especially for numerical problems ). How do you handle this problem?

Answer 1

You either:

1. Get the teacher's guide
2. Get someone to check your work
3. Find similar problems that you do have the answers for and use the same technique
4. You check your work, then check it again, and possibly again

I find teacher's guides are often quite useful for reasons beyond just the answers, though.

In addition, some textbooks have just the answers available under separate cover.

Lastly, try contacting the publisher to see what other classroom resources are available.
