Example

In operator.cc:

  C=A+B;
  cout << "A+B = \n" << C << endl;
  C-=B;
  cout << "A+B-B = \n" << C << endl;
  C/=A;
  cout << "(A+B-B)/A = \n" << C << endl;
  C*=B;
  cout << "((A+B-B)/A)*B = \n" << C << endl;
  C*=Num(5);
  cout << "(((A+B-B)/A)*B)*5.0 = \n" << C << endl;
  C+=Num(2);
  cout << "((((A+B-B)/A)*B)*5.0)+2.0 = \n" << C << endl;
  C-=A;
  cout << "(((((A+B-B)/A)*B)*5.0)+2.0)-A = \n" << C << endl;
