Type annotations link is fixed, thank you!

Just `__add__` doesn't work for me. I get:

    TypeError: unsupported operand type(s) for +: 'int' and 'Number'

Here's the code:

    class Number:
        def __add__(self, x):
            return 42 + x

    num = Number()
    print(num + num)

Edit: Okay. replacing `42 + x` with `x + 42` actually makes it work. But I'll be honest I have no idea what happened there.

It took me quite a long time to understand what happened there too!

(Pseudo code, let's call them num1 and num2 for better readability)

    num1 + num2 
    = num1.__add__(num2) 
    = num2 + 42 (that's why the order is important)
    = num2.__add__(42) 
    = 42 + 42 
    = 84

I'm not sure about that - it's still `<a href="mypy-guide">type annotations</a>` which jumps to https://sadh.life/post/builtins/mypy-guide and then jumps to your homepage.
