# What's the difference between multiply self or self.value inside the method?

Inside the rmul() method when I multiply other only by self it returns a numerical multiplication. On the order hand, if I multiply other by self.value it returns string multiplication. Whats the difference between the cases?

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)

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

return self + other

self.value = self + other
return self.value

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

def __rmul__(self, other):
return self * other

#    def __rmul__(self, other):
#        if '.' in self.value or '.' in other:
#            return float(self) * other
#        return int(self) * other
```
