Vedic mathematics is a relatively recent subject of study that requires integration with other areas of study. It is a collection of formulas taken from ancient Vedic scriptures. Here, we have combined Vedic mathematics with computer science. Specifically, we have created C++ programmes utilising two Vedic mathematics sutras: I. URDHVA TIRYAGBHYAM (Sutra-3) II. SQUARE BY DUPLEX (4-DIGITS). These two techniques speed up computations compared to more conventional techniques. We can discover the product and square of huge numbers with ease and with fewer errors when we use these two sutras.
