W-I-D-E on Wednesday: School/Education

This is almost the only litterature I have kept from my days at school.  It's from when I studied math at Stockholm University.

Why? I am soo intrigued by the title.  It implies that there might be a "Chamber's extended xxx mathematical tables"  I have never bothered to find out.  I think the thought is better than facts.

Why two copies? My wife also studied math.  Do we remember much of what we learned?  Hopefully a bit, but we have never felt the need to check with this book.  But you never know...

Many thanks to Steve for hosting this week.
