A class is usually bigger, has more methods and by convention we use self, other for instances and cls for classes.
By convention camel case should not used in methods. (The functions attached to the class, are methods).
Instead of doing the operation in one step, you can split it up.
First step: Get area of both rectangles
Second step: Add the area
A @property attached as decorator to a method of the class, just return the value without calling it.
class Rectangle():
"""
What does this class?
"""
def __init__(self, x, y):
"""
Here is how the object is initilized...
"""
self.x = x
self.y = y

def area(self):
"""

"""
return self.x * self.y
def __add__(self, other):
"""

"""
return self.area + other.area
def __sub__(self, other):
"""
Substract area of rectangle to area of other rectangle
"""
return self.area - other.area
def __mul__(self, scalar):

Multiply x and y of the rectangle by sclar and return a new.

def __truediv__(self, scalar):
