Answer 2

First I want to know what "sat" is all about.
The question is confusing with that word in front.
Commonse answer if the sat is ignored=
1. Perform these tasks in your head
2. Write them on paper
3. Use a calculator
4. Ask somebody else to do it and tell you the answer
5. Use the abacus, or multiplication table ( really old style)
