You also missed my point about k vs $k inside (( )). ((k=k+3)) works, (($k=$k+3)) does not since K gets substituted before anything starts calculating, so you end up trying to assign the value of 3 or something. Just plain variable names don't ever need a $ inside a (( )) expression anyway, why make them more complicated?
Well k is not guaranteed to behave the same way as $k inside an integer expression. It depends on the content of k. Example:
Returning to original question... Here is one way to get a number...
I think you should be able to expand it to get 2 numbers. And you seem to have a complete discussion on adding them.

command-not-found
COMMAND-NOT-FOUND(1) http://en.opensuse.org/Sco COMMAND-NOT-FOUND(1)NAME
command-not-found - A command-not-found handler
SYNOPSIS
command-not-found {binary_name} {repository}
ARGUMENTS
The following arguments are required:
binary_name
The name of binary you are looking for.
repository
The name of repository for search. For most cases, use zypp
DESCRIPTION
command-not-found handler is designed to tell users which package contains a missing command.
The handler is integrated to bash(1) and zsh(1) shells and is not necessary to call it directly. Just type a name of the command in your
favourite shell and you'll get a result.
If you consider c-n-f handler useless, just add unset command_not_found_handle to your profile or remove the command-not-found package.
Handler doesn't call the command-not-found binary directly, it only prints info about it. If you want to invoke it automatically, just add
export COMMAND_NOT_FOUND_AUTO=1 to your bash profile.
EXAMPLE : NORMAL USAGE
For example you want to try blender, because you have heard that is an amazing program. So just type blender in shell:
$ blender
You get the following output:
The program 'blender' can be found in the following package:
* blender [ path: /usr/bin/blender, repository: zypp (openSUSE 11.1-0) ]
Try installing with:
sudo zypper install blender
bash: blender: command not found
