Oh, that changes _everything_, _everything_ I am sure.

When at that time in my life when I had been attending lectures some
professor would have stated

"As an example, let's see how to take the inverse of the matrix
( 1  2 )
( 2  1 )"

I would never felt the urge to tell the professor that this is a
particular matrix I never actually needed to invert.  I'm pretty sure
that the entire lecture room would have bursted into laughter at me
volunteering this particular bit of information and considering it
important enough to ask for everybody's attention.

It is an example.  Nobody expects life-shattering relevance of that
example for any purpose but being an example.
