n is pie...

There is no way, using the formula editor will only become an unsent image...

There is one missing multiple-choice question, because the question is printed and cannot be seen clearly, so don’t care.

And it's very boring, I can't open the book review... So I can only see the first two lines of the things... and there are no spaces...
