Math Tool

Hi all,
I am new to PERL scripts, and i have made my first script which i am posting here.
This math tool performs all basic arithmatic functions.


Code:
#!/usr/bin/perl
print "\t----------Welcome to Maths Tool-----------\n";
do
{
print "Enter your choice :";
print "\n\t1)Addition\n\t2)Subtraction\n\t3)Multiplication\n\t4)division\n";
$a = <>;
if ($a == 1)
{
print "\nHow many numbers you wanna add...??\t";
chomp($b = <>);
print "Enter $b numbers : \n";
for ($count = 1; $count <= $b; $count++)
{
$c = <>;
$d = $d + $c;
}
print "Addition is : $d\n";
}
elsif ($a == 2)
{
print "\nEnter two numbers to subtract :\n";
$b = <>;
$c = <>;
$d = $b - $c;
print "Subtraction is : $d\n";
}
elsif ($a == 3)
{
print "\nHow many numbers you wanna multiply...??";
chomp($b = <>);
$d = 1;
print "\nEnter $b numbers : \n";
for ($count = 1; $count <= $b; $count++)
{
$c = <>;
$d = $d * $c;
}
print "Multiplicationn is : $d\n";
}
elsif ($a ==4)
{
print "\nEnter two numbers to subtract :\n";
$b = <>;
$c = <>;
$d = $b / $c;
print "Division is : $d\n";
}
else
{
print "\nWRONG CHOICE!\n";
}
print "\nDo u want to continue <y/n>";
chomp($var = <>);
} while($var eq "y");
print "\n\t------------Thanks for using Maths Tool--------------\n\n";


PS : This is really a very simple code but its my first one. So I just wanted to know your opinions and comments about it.

Thanks.

ASP-PERL(1p)						User Contributed Perl Documentation					      ASP-PERL(1p)

NAME
asp-perl - Apache::ASP CGI and command line script processor SYNOPSIS
asp-perl [-hsdb] [-f asp.conf] [-o directory] file1 @arguments file2 @arguments ... -h Help you are getting now! -f Specify an alternate configuration file other than ./asp.conf -s Setup $Session and $Application state for script. -d Set to debug code upon errors. -b Only return body of document, no headers. -o Output directory, writes to files there instead of STDOUT -p GlobalPackage config, what perl package are the scripts compiled in. DESCRIPTION
This program will run Apache::ASP scripts from the command line. Each file that is specified will be run, and the $Request->QueryString() and $Request->Form() data will be initialized by the @arguments following the script file name. The @arguments will be written as space separated words, and will be initialized as an associate array where %arguments = @arguments. As an example: asp-perl file.asp key1 value1 key2 value2 would be similar to calling the file.asp in a web environment like /file.asp?key1=value1&key2=value2 The asp.conf script will be read from the current directory for parameters that would be set with PerlSetVar normally under mod_perl. For more information on how to configure the asp.conf file, please see < http://www.apache-asp.org/cgi.html > SEE ALSO
