## MSC #30 – “By Inspection”

We reserved this Sutra for the last of our 30 MATH-Inic Specials for Christmas because it depends largely on how much one has mastered the concepts presented in the previous specials. It also encourages adaptation and stimulates creativity because it…

## MSC #29. Recurring decimals.

Our 29th MATH-Inic Special for Christmas is about a “fun, fast and easy” way to convert a fraction with a prime number denominator into a recurring decimal. In our example here, instead of dividing by 19, we will use its…

## MSC #28- By Addition and By Subtraction: Solving simultaneous equations.

Our 28th MATH-Inic Special for Christmas is the use of the Sutra ”By Addition and By Subtraction” in solving simultaneous linear equations. Using this Sutra, we can easily eliminate a variable. This is especially handy in cases where the coefficients…

## MSC # 27- Transpose and Apply

The Vedic Mathematics Sutra or word formula “Transpose and Apply” has a much wider application than the “transposition” which we know in Algebra as a short cut of the “golden rule’ of Algebra: do unto one side of the equation,…

## MSC #26 – The Duplex and its Extensions.

The Duplex is an important devise in squaring numbers and polynomials, extracting square roots and solving quadratic equations. Its principles can be extended into triplex and beyond. The duplex of a number with an even number of digits is twice…

## MSC #25 – Counting Events: Labeling Technique

Merry Christmas! Our 25th MATH-Inic Special for Christmas is not of Vedic Math origin but it definitely adheres to the Vedic ideal of “at-sight-one-line-mental-solution”. I learned this technique from the video lessons of James Tanton, the resident mathematician at the…

## MSC #24 – Vertically and Crosswise: Working with Fractions and Mixed Numbers

Our 24th MATH-Inic Special for Christmas is about multiplication of mixed numbers. We were trained to convert mixed numbers into improper fractions first before performing multiplication and later change the product into mixed numbers. Oftentimes direct application of the distributive…

## MSC #23 – Proportionately: Partitive solution

Our 23rd MATH-Inic Special for Christmas is my personal favorite and I think will draw the most comments. I originally titled it the “See Saw Solution” the reason for which you will realize later. I use it to mentally solve…

## MSC #22 – Using the Average: the Difference Of Two Squares(DOTS)

Our MATH-Inic Special for today is the other half of “Using the average”. This time we will start with the difference of two squares: a2 – b2 = (a + b) (a – c).  According to Sri Bharati Tirthaji, given…

## MSC #20 – Arithmetic Sequence: Counting Terms

If you were asked how many numbers are there from 26 to 89, would you try to recall the formula taught to us in grade school or would you actually count it? But if you were asked how many numbers…
