Numbers near 50 can also be squared easily. This time, however, we add the excess or subtract the deficiency from 25 and not from the number. The second part is still equal to the square of the excess or deficiency.…
We have seen how simple Nikhilam multiplication can be when applied to numbers above a base and numbers below a base. Now we can see that the same principles can be used in multiplication where one number is above and…
Squaring a number below a base is difficult using the conventional methods because usually, large digits are involved but a Vedic Math sub-Sutra or word formula which states that “whatever the deficiency, lessen by that amount and set-up the square…
When multiplying numbers below a power of 10, we subtract one number’s deficiency from the base from the other number and then get the product of the deficiencies. Similar to base multiplication of numbers above the base, the second part…
One special application of base multiplication is squaring numbers near a power of 10. To square a number just above a power of 10, we apply the Vedic word formula, “Whatever the excess, increase by that amount and set-up the…
Our first Vedic Mathematics Olympiad (VMO) tip for the primary level is about NIkhilam or base Multiplication, a fun fast and easy way to do multiplication of numbers close to bases. In VM powers of 10 are often used as…
Any whole number can be expressed as a product of two whole numbers. If the number is prime, it can be expressed as a product of itself and 1. The algebraic formula a2 – b2 = (a + b)(a –…
While studying Pythagorean Triples, I came across an article about two consecutive odd (or even) numbers being the basis for the lengths of the sides of right triangles. The sum of these numbers would be one of the legs of…
I wrote to Dr. Po-Shen Loh that I previously used a method similar to his "new approach", and in response, he gave me an address where we can chat. Dr Po-Shen Loh sent me the following links: https://www.poshenloh.com/quadraticrelated, where he…
Dr. Po-Shen Loh, in his YouTube video, “A different way to solve quadratic equations”( https://www.youtube.com/watch?v=ZBalWWHYFQc) mentioned about studying the works of the ancient Babylonians, 15th- century Mathematicians and even works of Indians. He found out that the key points of…
