# Challenge Task 2 of 2 Now wrap it up by adding in __imul__, which does in-place multiplication. Be sure to update self.

i really dot get 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)

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.value = self.value * other
return self.value
```

MOD

You are close to having the correct answer. The goal of `__imul__` is to retain the object type of `self.value` as a `str`.

Let's break down what you've tried:

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

Since `self.value` is a string, multiplying it by a integer will result in a repeated string, not a new string containing the updated number. With the `__mul__` method is available, use it to do the multiplication. To trigger the use of `__mul__`, use `self` as the multiplicand in place of `self.value`. This gives us:

```        self.value = self * other
```

One drawback is `__mul__` returns an integer instead of string. To fix this, wrap the multiplication with `str()`:

```        self.value = str(self * other)
```

Post back if you need more help. Good luck!!

thank you id figure it out :D
