Oh, good bug-find. Here's a couple of fixes that you've prolly already done

1. To get it to do the multiple @ operators at the same level you need to 

use Regexp::Common

Then replace the 'Precedence 5' regexp with: 
$term=~s/(\d+)@($RE{balanced}{-parens=>'[]'})/rpt($1,$2)/eg;

[download]

2.To get it to do the * and / from left to right, change 'Precedence 3' to this single regexp: 

$term=~s/(\d+)([\*\/])(\d+)/int(eval("$1$2$3"))/eg;

[download]
and change 'Precedence 4' to 
$term=~s/(\d+)([+-])(\d+)/eval("$1$2$3")/eg;

[download]

Hope these help you with your efforts. There is still no syntax checking but I figure you can handle stopping people from putting 3*+/4. Oh, and you probably want to handle negative numbers before 'Precedence 4'
