You have a couple of errors, and don't forget to use warnings; and use strict;
First, you forgot a comma after 'ne' in your first pack.
Predeclare %button, and get rid of the my before $button{$i}.
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
my $mw = new MainWindow;
$mw->geometry("300x300");
my %button;
my $ans = 'foobar';
my $num_screen = $mw->Entry(-width => 40, -state => 'disabled',
-textvariable => "$ans")
->pack(-pady => 30, -anchor => 'ne', -side => 'top');
my @buttons = ( '9','8','7','6','5','4','3','2','1','0');
for (my $i = 9; $i >= 0; $i--)
{
$button{$i} = $mw->Button(
-text => "$buttons[$i]",
-width => '3',
-height => '3',
#-command => &numpress($i))
)->pack(-anchor => 'nw', -side => 'top');
}
MainLoop;
