expr is considered generally antiquated. It is best to use for arithmetic
operations
the shell $((..)).
To quote POSIX:
"The expr utility has a rather difficult syntax [...] In many cases, the
arithmetic
and string features provided as part of the shell command language are
easier to use
than their equivalents in expr. Newly written scripts should avoid expr in
favor of
the new features within the shell."
