mul and rmul Methods in Class - Why doesn't it follow the same structure as addition?

I've written the code following the same structure as for addition. This seems to return an error. Could anyone explain why?

numstring.py
class NumString:
    def __init__(self, value):
        self.value = str(value)

    def __str__(self):
         return self.value

    def __int__(self):
        return int(self.value)

    def __float__(self):
        return float(self.value)

    def __add__(self, other):
        if '.' in self.value:
            return float(self) + other
        return int(self) + other

    def __radd__(self, other):
        return self + other

    def __iadd__(self, other):
        self.value = self + other
        return self.value

    def __add__(self, other):
        if '.' in self.value:
            return float(self) * other
        return int(self) * other

    def __radd__(self, other):
        if '.' in self.value:
            return float(self) * other
        return int(self) * other

Ohโ€ฆ you didn't rename the new methods to __mul__ and __rmul__, so you're currently overriding the __add__ and __radd__ methods!
