## 30MSC 2023 #30: By Mere Observation

We reserved the easiest strategy for the last because its application depends on how many types of mental calculations you have mastered. The answers to many problems (especially multiple choice problems) can be determined without really solving - just by…

## 30MSC 2023 #29:Triples.

A triple is a set of three numbers which satisfies the Pythagorean Theorem: a^2 + b^2 = c^2, that is, the sum of the squares of the first two numbers is equal to the square of the third. Whereas, in…

## 30MSC 2023 #28: Specific and General

We often generalize from specific observations. We study the relations of numbers in sequences and formulate general rules to describe the pattern and later use those rules to get specific values for certain terms in the sequence. Algebra is a…

## 30MSC 2023 #27: Vedic Methods of Solving Quadratic Equations.

When a quadratic equation cannot be easily factored, a technique called completing the square is used. However, this method is tedious and difficult for most students. The quadratic formula,  which is derived by completing the square, is often used instead.…

## 30MSC 2023 #26: Using Vertically and Crosswise on Fractions and Mixed Numbers

The conventional way of multiplying mixed numbers is to first convert them into improper fractions then follow the usual way of multiplying fractions (numerator x numerator/denominator x denominator) and then converting back the product into a mixed number. This works…

## 30MSC 2023 #25: Using the Average

(I am reposting this article from December 2022 to show the power of Vedic Math Sutras.) On Dec 12, 2019, a YouTube video “A Different Way To Solve Quadratic Equations” at https://www.youtube.com/watch?v=ZBalWWHYFQc) was published by Dr. Po-Shen Loh, a Carnegie Mellon…

## 30MSC 2023 #24: By Addition and By Subtraction

Only a few problems in Math do not require addition or subtraction at some point in their solutions. In many types, however, the sutra “By Addition and By Subtraction” play a major role. Almost all divisibility rules, for example, are…

## 30MSC 2023 #23: Think of a Number

In the foreword to our book “Algebra Made Easy as Arithmetic”, Kenneth Williams, the foremost authority in Vedic Math today, wrote: “It is good to see the appearance of this book as it shows how the simple processes we all…

## 30MSC 2023 #22: Sequences

A sequence is a list of numbers that usually follow a particular pattern. The pattern may be increasing, decreasing, or recurring. To know the missing terms in a sequence we have to know the rules defining the terms of the…

## 30MSC 2023 #21: Counting

Counting is, perhaps, everyone’s first lesson in Math. It is used to determine the number of elements or objects in a group or set. But there are techniques for counting without really counting. This question from the Junior IVMO 2021…
