Answer: Maple has a global variable called printlevel. This controls
how much information is printed. The default setting is 1. At this setting
only statements one nested level or less away from the top level will echo
their results. In our example we would need to raise the printlevel to 2.
this can be easily done by assigning 2 to the global
variable printlevel.
This could cause other information to appear. See the help page for
printlevel for details on how it affects other information messages
and procedures.
