Hello @qasim78,

Me smj sakta hun k apny bht mehnat se blog ko likh ha, magar wo professor hain or wo janty hain kia galat ha or kia sahi ha. Jo jis husab se likhy ga usko us tarah k hi number mily gay. Hamko galtio se sikhna chaye. Or mje umeed ha k ap galtio se sikho gay, kisi b kism ki madad k liye ap mujse rabta kar sakty ho. Shurkia.

Regards,
