Mental Mathematics
Enayatullah Maleki
Mental mathematics is the process of doing basic mathematics off the top of your head, without the use of paper and pencil, or an electronic device, with the help of Mental Mathematics; you kill two birds with one stone, keep the brain fresh and sharp, and improve your math ability.
