Im confused how to use __mul__ and __rmul__

I'm not sure how to use mul and rmul on this question.

It gives me an error whenever I make a method for it.

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

Hint: the existing methods for "add" and "radd" could be used as a model, just use the appropriate math operator.
