Well to add the 10 and NA you will need to convert NA to an integre/number. So the following should do the job:
php Syntax (Toggle Plain Text) 
  1. $var1=str_replace('NA',0,$_GET['input1']);
  2. $var2=str_replace('NA',0,$_GET['input2']);
  3. $var3=str_replace('NA',0,$_GET['input3']);
  4. $var4=str_replace('NA',0,$_GET['input4']);
  5. if (($var1+$var2)>($var3+$var4)) {
  6. //blah
  7. }
However you may want to replace $_GET with whatever you already have in place.
Try not to bump 10 year old threads as it can be really annoying.

PHP Syntax (Toggle Plain Text) 
  1.  echo $var1=10+"NA";
  2.    echo"<br>".$var2=10+20;

Output :-
10
30

And i want to show that
10+"NA" > 10+20

I tested the if statement you've suggested and no error occured so I don't see what the problem is. Below is an example of my script.
php Syntax (Toggle Plain Text) 
  1. <?
  2. if (10+"NA" > 10+20) {
  3. echo 'passed if';
  4. } else {
  5. echo 'failed if';
  6. }
  7. ?>

Hi, cwarn23

Out put out your program is :- failed if

I want here output :- passed if

I give the explanation what i want
10 + "Na"= 10 and 10 +20=30
But NA means not applicable we can't consider as value
so we use as 10+20 i.e 30 in processing.

So i want to show (10+"NA") > (10+20)
How to do this????

If you just want the opposite result then the following should do the job.
php Syntax (Toggle Plain Text) 
  1. <?
  2. if (10+"NA" < 10+20) {
  3. echo 'passed if';
  4. } else {
  5. echo 'failed if';
  6. }
  7. ?>
