Can I simplified the operator(addition/multiplication) overload via C++

I make a class about Complex addition,but I found it was kinda tedious to write the overload function. my code(c++11) is as follows:

#include <iostream>
class complex{
public:
    complex(double real,double imag);
    complex();
    friend complex operator +(const double &m, const complex &origin);
    friend complex operator +(const complex &origin, const double &m);
    double real;
    double imag;
};
complex::complex(double real,double imag):real(real),imag(imag){;};
complex::complex():real(0),imag(0){;};
complex operator +(const double &m,const complex &origin){
    complex p;
    p.real=origin.real+m;
    p.imag=origin.imag;
    return p;
}
complex operator +(const complex &origin,const double &m){
    return m+origin;
}




int main() {
    complex com(1,2);
    com=3.+com;
    com=com+3.;
    return 0;
}

can I do the addition of Complex with one operator function by using my class(anyway I DON'T WANNA use standard library of )? thanks.
