Hello,
first you need to create your input fields, in this case weight, that you will receive at the code section as $weight. Then you can write your math at the code section and introduce the result into your variable (if you call it 'result', then you need to fill the $result variable, for ex):

$result=$weight*5;

For your case you also need to use 'if' clauses, so you can check the proper syntax here:

https://www.php.net/manual/en/control-structures.if.php

In order to build this kind of code

if($weight<10) {
$result=......;
}
if(.....condition...){
.....
}

And finally, you can write your result at the output section with

##result##

tag.

Hope this helps, regards
