My first advice would be to concentrate. Your sloppy typing - no matter if English is your first language or not - in the template does not persuade me (at least) that you are really interested in what you do. And one of the main rules in computing is: garbage in, garbage out.
Having said that, let me comment on your code:
You have two code snippets of which a large part is nearly identical. That's good. Make that part one - the central - block of your program, and massage the input variables, be they command line parameters to the script or interactively entered on the keyboard, so they fit the needs of your main block. Input validation would be part of that as well.
You have a "first" variable, and you have the command line parameter $1. Any idea about how to transform or combine them into one input to the main block?
And then, wouldn't it be nice to get an - optimally correct - result from your calculator? I can see that calculation only in half of your equations. Reconsider.

For your line numbers, try cat -n

DEBCONF-MERGETEMPLATE(1)					      Debconf						  DEBCONF-MERGETEMPLATE(1)

NAME
debconf-mergetemplate - merge together multiple debconf template files SYNOPSIS
debconf-mergetemplate [options] [templates.ll ...] templates DESCRIPTION
Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program. This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified files will be read in, merged, and output to standard output. This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the english versions of the fields they translated, for their reference. So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the main file (which might be more up-to-date). This program handles that case properly, just list each of the translated templates files, and then your main templates file last. OPTIONS
--outdated Merge in even outdated translations. The default is to drop them with a warning message. --drop-old-templates If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire template. SEE ALSO
