# Now wrap it up by adding in __imul__, which does in-place multiplication. Be sure to update self.value!

I got to the second part of the challenge and even read the other posts about this question.. but I wasn't able to pass the challenge. I didn't understand these instructions.. nor the advice that the mods are recommending:

"You are very close. Notice how in the in-place method iadd, the value of self.value is updated before the return. This is what makes it work in place: the object value changes and is not just used to return a value. Add assignments to self.value and it should pass. Post back if you have more questions! Good luck!!"

^^I have no idea what that means... can someone help?

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) * other
def __rmul__(self, other):
return self * other
def __imul__(self, other):
self.other = self * other
return self.other
```

```def __imul__(self, other):
