Shuni  ta’kidlab  o’tish  kerakki  double+complex  tipidagi  qo’shishni  bu  usulda 
qo’shimcha yuklash mumkin emas. 
Sinfdan tashqari yuklanadigan operatsiyalar ikkita operandga ega bo’lishi kerak. 
Ulardan biri sinf tipiga ega bo’lishi lozim. 
Qiymat  qaytarish  uchun  vaqtinchalik  o’zgaruvchidan  foydalaniladi.  Bu 
maqsadda konstruktordan:
