You are concatenating strings so this is expected. Either drop the '
(or use parseInt)

function Ctrl($resource){
this.items= parseInt('333');
this.next= 11;
}

Btw, you want to always provide the radix when using parseInt

parseInt('333', 10);

An ugly solution is like this:
{{items*1 + next*1}}

Better, if you create a new model and display that, but you need to
manually keep this new model up-to-date:
this.sum = parseInt(this.items) + parseInt(this.next)

Or you can create an add() function in your model, and use that in your view:
{{add(items, next)}}

Anyway, it is not angular issue. This is how javascript works when you
add two strings.

Was a bit quick on the trigger there, if you really want to do the
conversion in the template you could expose parseInt in the scope.

But I would strongly recommend against this! Better to keep this kind
of logic in the controller. Why do you want to add the numbers? Create
a function and name it appropriately and you have testable code :-)

lastly, your are dealing with user input that should be converted from string to number you should use formatters: http://docs.angularjs.org/#!/api/angular.formatter.number
