I'm interested in "expr" and "bc".
The man pages lack reasonable examples.
The tutorial/HOWTO pages confuse the issue with fancy page layouts

Browsing the site I found some unintended humor - "The behavior of
binary arithmetic operators depends on whether they're used on numbers
or strings." http://learn.perl.org/faq/perlfaq4.html
That's not unintended humor, that's a bug in the documentation. It
should say:
"The behavior of bitwise operators depends on whether they're
used on numbers or strings."
I've filed a bug report -- thanks for the tip.
More seriously, the site demonstrates to convey useful information to
different audiences. I suspect I'm going get even less sleep ;>
Thank you.
YW. If you're interested in Perl 5, "Learning Perl" is the canonical
introductory text:
