As you know that GRE, GMAT and SAT contain a quantitative section which tests our mathematics skills, our ability to perform simple mathematics calculations with high speed and accuracy because of the limited time, ofcourse you can use calculators for the SAT questions but what about GMAT and GRE where you are not aloowed to use one? If you have to perform complicated calculations such as multiplication of large digits, although you can do this by the same multiplication process but it will take too much time and even in the SAT you have no need to run for calculators for the simlest of calculations which you can perform in your head quite easily. This is a major problem with a simple solution that is Vedic Mathematics, which allows you to perform simple math calculations in your head hence saving you the need to run for calculators!
