I can't see this being an issue with the "calculator app", unless the
calculator app itself is written to perform file globbing.
It /might/ be an issue with the shell, if you permit it to glob
the "calculator app" arguments before invoking the "calculator app" binary.
But, then again, Unix shell filename globbing is something that the user can
disable temporarily or permanently if necessary.
sh -o noglob -c "calculate 3*5"
sh -o noglob

Only if shell globbing is enabled, and you don't specifically bypass it.
