Answer 1

`input` function returns a string, you need to convert them into a type that supports arithmetic operations.

If you want the numbers as integers (whole number) use int() as follows:
x = int(input("First Number"))
y = int(input("Second Number"))

And if you want the numbers as floating point (fractal number) use float() as follows:
x = float(input("First Number"))
y = float(input("Second Number"))
