I've been working on a practice assignment for a while now, and can't figure out the difference between the two. It's just practice, not graded. It's a pre-chapter assignment, and I have no idea what I am doing.

To evaluate means to find what the sum converges to.

Do you have a specific problem in mind?

For instance, if we were to evaluate:

\sum_{n=1}^{\infty}\frac{1}{10^{n}}, we would find its sum is 1/9.

No, it's not really the problems themselves.. It's understand what I am doing? I don't know if that makes sense, I can do the problems.. But don't understand the definitions of what I am doing.. Does that make sense?

No, I am sorry. Perhaps, If I saw something specific.
