# Incorrect code in __mul__ __rmul__ challenge.

Hi. I'm not too sure why this is incorrect, can anyone advise?

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):
return self * other

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

Hi there, Jordan young ! Before you can multiply a string by a number, you need to first convert it to an `int`. So where you have `self * other`, you need `int(self) * other`.

Hope this helps!

Hi Jennifer, This does make sense.

However after doing that, I am returned with this error " Can't multiply a number with a `NumString` (i.e. `10 * NumString`)"

my code update is as follows: def mul (self, other): return int(self) * other

```def __rmmul__ (self, other):
return int(self) * other
```

This was an especially confusing error as I thought that int placement converts the string like your message suggests.

Is there a mistake somewhere in the code above that I previously had used?

Hi again, Jordan young ! You have a typo in the definition of your method.

You typed:

```def __rmmul__(self, other):
```

But you meant to type:

```def __rmul__(self, other):
```

Note that your version contains two "m"s where as the correct version contains one "m"

Hope this helps!

This is indeed solved.

Grrr don't you hate it when that happens?

Thank you :)
