# Vedic Math Sutra: Sutra-14 Ekanyunena Purvena

## |

Since mathematics has always been essential to our lives, kids must have a solid foundation. While learning math through traditional ways might occasionally feel difficult, Vedic Mathematics offers a unique and fascinating approach that can make learning math for youngsters pleasant and exciting.

Ekanyunena Purvena, which helps kids to execute fast calculations efficiently, is one of the essential Vedic Maths concepts and is the sub-sutra to Nikhilam, Ekanyunena Purvena, and has the meaning of “one less than the previous” OR “one less than the one before.”

Only a few situations can be applied to this sutra, and they must meet strict requirements. Such as, a number that needs to be multiplied (the multiplicand/multiplier) only has nine digits. For instance, 999, 99999, 99999999, and so forth.

The condition mentioned above is possible only in three different situations.

#### Case 1. Both numbers contain an equal number of digits.

Example: 2463 x 9999

Step 1:

To obtain the left part of the answer, you deduct 1 from the Multiplicand using the Ekanyunena Purvena method.

2463 – 1 = 2462

Step 2:

To determine the right part of the answer, subtract the left part obtained in Step 1 from the multiplier.

9999- 2462 = 7537

Thus, 2463 × 9999 = 24627537

#### Case 2. Suppose the number of digits in one of the numbers is smaller than the count of 9s in the second number.

Example: 347 x 9999

Step 1:

By subtracting 1 from the Multiplicand, the left part of the answer is derived using the Ekanyunena Purvena method.

347-1 = 346

Step 2:

To obtain the right part of the answer, subtract the left part obtained in Step 1 from the multiplier.

9999 – 346 = 9653

Thus, 347 × 9999 = 3469653

#### Case 3. Suppose the number of digits in one of the numbers exceeds the count of 9s in the second number.

Example: 266 x 99

Step1. Due to two 9s in the multiplier, we multiply the Multiplicand by 100, representing the two zeroes in the result.

266 × 100 = 26600

Next, deduct the Multiplicand from the product obtained in step 1.

26600 – 266 = 26334

Thus, 266 × 99 = 26334

#### Wrapping Up!!

The Ekanyunena Purvena is a beneficial method that enables kids to calculate things with ease mentally. This technique can be used in mathematics to help kids solve problems more easily.

Patience, encouragement, and tailoring the learning process to each child’s particular skills and learning preferences are all essential for successfully transferring this Vedic knowledge.

85^2 = 8 × 9/5 × 5 = 72/25 = 7225… try exploring using this
