 Create a constructor function `Calculator` that creates objects with 3 methods:
 
-- `read()` asks for two values using `prompt` and stores each of them in a unique object property.
+- `read()` prompts for two values and saves them as object properties with names `a` and `b` respectively.
 - `sum()` returns the sum of these properties.
 - `mul()` returns the multiplication product of these properties.
