At First be clear that your HandleError attribute will have no effect on debug mode, only in release mode with debug set to false in web.config they will run.
If any error comes within the Action method then the most specific error , in your case Arthimetic is more specific than general exception , so it will run and respective view will be served.

Hi,

You can put debugger and debug your code. write code to Raise exception inside try block and check which get call first. Debuggin is best to check your doubt.

If you have both togather then Try catch will take preference. Please check using debugger so you will come to know what exactly happening there.

one more thing for HandleError attribute has order if you want to specify order of execution,

It will raise a compile time error like "not all code paths return a value".
