Why can I not use operator overloading for classes?

I hope this helps . It is possible to use operator overloading only for records, not for classes in Delphi for Windows.

What if -> operator do not return the reference like dot . operator? Will this stop overloading -> operator as wel

it fixes the issue I only understood how overloading the operator-> works, after reading this:
struct X { int foo; };

struct Y {
    X x;
    X* operator->() { return &x; } // returns pointer 
};

struct Z {
    Y y;
    Y& operator->() { return y; } // returns reference
};

Z z;
z->foo = 42;          // Works!

Overloading operator += with two classes

I hope this helps you .
Is there any way to achieve my goal without actually overloading operator+ for class B?

Arithmetic operator overloading for class template, the operator should take two classes of different types

Hope this helps Your overloaded operator+ function takes two const fraction& arguments. The problem is that the two arguments you use are of different type, the T template for each are different.
To begin solving it you need to use different types for each argument, which means two template arguments. You also need to have a common type for the returned faction object.
template <typename U, typename V>
fraction<std::common_type_t<U, V>> operator+(const fraction<U>& fraction1, const fraction<V>& fraction2)
{
    fraction<std::common_type_t<U, V>> temp;

    // ...

    return temp;
}
