Hi,

 

You can achieve this using Formula field which exacty suite for your requirment.

 

But if still you want to do this using trigger, find below code.

 

Trigger addtrigger on customobject__C(before insert, before update)
{
  if(Trigger.isBefore) 
  {
    if (Trigger.isInsert || Trigger.isUpdate)
     {
       for(customobject__c cob : trigger.new)
         {
            cob.result = cob.num1+cob.num2; 
           }
       }
    }
}

 Here replace Customobject__c with your custom onject name.

First make the class and add the calculation logic then make a trigger on your save or submit button. And then call that class in the trigger by using appropriate parameter.
