As math has always been a part of our lives, kids need a good base. Although learning maths in the usual ways sometimes may become tough, Vedic Mathematics provides a completely different and exciting method that could make learning math for young children a fun-filled and enjoyable task.
Well-structured exercises and techniques that the Vedic Maths Workbooks for Level 14 provide really help children absorb the complex concept easily and confidently.
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.”
Ekanyunena Purvena is used for simplifying complex multiplication and subtraction problems, making calculations quicker and easier.
Only such a handful of situations can be used here that strictly come under the above requirement. For instance, only a number that is to be multiplied (the multiplicand/multiplier) contains nine digits. For example, 999, 99999, 99999999, and so on.
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 get the left part of the answer, you subtract 1 from the Multiplicand following 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
Therefore, 347 × 9999 = 3469653
Case 3.If the number of digits in one of the numbers ismore than that of count of 9s in the other number,
Example: 266 x 99
Step1. Since there are two 9’s in the multiplier, we multiply the Multiplicand by 100 because of the two zeroes in the answer.
266 × 100 = 26600
Now, subtract the multiplicand from the product found in step 1.
26600 – 266 = 26334
Thus, 266 × 99 = 26334
Wrapping Up!!
Ekanyunena Purvena is a useful technique that lets children compute numbers mentally easily. This technique can be applied in mathematics, enabling kids to solve problems with ease. Ekanyunena Purvena is used for simplifying complex mathematical computative work, particularly in subtraction and multiplication, which makes mental computation faster and easier for children.
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.

What is the square of 85 by using the formula Ekadhikena Purvena… I can’t solve it.
85^2 = 8 × 9/5 × 5 = 72/25 = 7225… try exploring using this
For what other problems can we use Ekadhikena Purvena???
We can use it to find the square of complicated numbers.
