overloading binary + operator

I need some help or a suggestion please

I have a template class in which I am trying to implement the following:

myClass + 'any type variable';

where 'any type variable' lets say for this example is '10' is added to a private member vector (called temp) in myClass

So say before the vector was 5,7,8 the (+ 10) would just add 10 to the end of the vector so it would now have 5,7,8,10

I also need to be able to chain the operation so
myClass + 10 + 11 + 12; would result in:
5,7,8,10,11,12

Code:

---

template<typename T>
myClass<T> operator + (***WHAT GOES HERE**)         
{
        temp.push_back( **WHAT GOES HERE**);               
        return *this;       

}

---

any help would be appreciated

Code:

---

template<typename T>
myClass<T> operator + (T item)       
{
        temp.push_back( item);               
        return *this;       

}

---

or something like that depending on what temp.push_back does
