Did i confuse the integer data type with something else?

Question

I dont know how to deal with the error of unsupported operand types: int + App\Models\Rating but the calculation works just correctly. It pinpoints the error to the public function rate starting from this currentRating = round. Im confused because it's new to me in terms of the language so it's big blur.

     <div class="w-full space-y-5">
         <p class="font-medium text-blue-500 uppercase">
             Rating: <strong>{{ $currentRating }}</strong> ⭐ 
         </p>
     </div>

You probably meant to write + $rating->rating instead of + $rating.

$rating is an object, not an integer.
