Hi
@berkeman,
@jedishrfu. I got to Amazon via the PF link, I translated, and I had everything ready: the title, the edition required, the ISBN, wrote down from Pearson publishing house, a credit card...
Both my brother and I just didn't manage to find how or where order at the website the textbook "Calculus: a complete course, 9th edition, by Robert A. Adams and Christopher Essex". We didn't achieve. These were the steps:
1- Get into PF
2- Link

3- Access Amazon
4- Translate into Spanish
5- Here comes the problem: no way, nowhere, nohow, write down the order; just introduce the title.
I know it's my incompetence.
I've got the Spanish 6th edition; my intention might seem nonsense, but the reasons are the following:
I want to improve my participation in PF, learn English, American.
The textbook I own has disappointed me: I spent a lot of time when, in my personal opinion, led to confusion with Intermediate Value Theorem and Mean Value Theorem.
Thanks, love. Any question or suggestion, or reproach, welcomed
