SageMath giving NameError on predefined functions

I am following Abstract Algebra an Interactive Approach by William Paulsen but some of the functions in the first chapter itself, like ShowTerry(), ItitTerry(), MultTable() etc are giving NameError. Same is the case with most of the functions in the preliminaries chapter like ShowRationals(), PowerMod()
I'm not really sure how to go about it. I even tried installing sage from Source Code but the problem persists. Do I have to install some separate group theory package or am I missing something here?

These functions are not part of SageMath itself. They are functions defined by the book's author.

I have not seen the book, but maybe the function definitions are given in the book, and can be copied from there.

It is also possible that you can get them from the book's courseware, on the author's webpage:
