"Read two numbers from the digital scanner and return their combined total weight."

Real-World Metaphor:

Think of a supermarket barcode scale. A bag of apples weighs 10 units, and a bag of oranges weighs 20 units. When both are placed on the scale, the digital display combines them and outputs 30.

### The Mission Imagine you are building a digital scanner at an automated parcel depot. The scanner reads two weight sensors simultaneously: sensor **x** and sensor **y**. Your job is simple: take the two recorded numbers, compute their combined weight, and send that final number across the bridge to the sorting bay. ### Rules of the Depot - Receive two integers: `x` and `y`. - Return the sum of `x + y`. - Do not return text or strings — return the numerical sum directly.
