in thread Illegal subroutine

Do read perlsub if you meant to make a function. There are math examples you may emulate within perlsub (just search for the string "cube_root" within perlsub to get a feel for what you're trying to accomplish).

FWIW,if you were not trying to create a function, and instead merely set a variable to calculate profit you would have the following (note: I changed the equation a lot):

my $net = 123.456; my $coffee_allowance = 100.00; my $profit = ( $net - $coffee_allowance ); my $step_three = $profit; print "profit = $step_three \n";
(minor code updates)
