The question itself is very easy, once you obtain the scientific definition of the word "parent".
Calculators and other processors are faster in math becose you can design them to do that particular job. On the other hand, human brain was not designed (evolved..) to calculate math fast or at all, and the brain is not that good on learning new "software", so its pretty slow on tasks like these.
