Question 1090814
.
This text is difficult to understand, because of bad wording.


As I understand, this assignment is not from a textbook (no one textbook will place such a text).


My feeling is that somebody tries to create his own problem.


There is nothing bad in it.


The only problem is to do it correctly.

Good luck and happy learning !!
