Three Popular Vedic Mathematics Shortcuts  Using Vedic Mathematics

Urdhva-Tiryagbhyam (Vertically and Crosswise):

Vedic Method:

The Urdhva-Tiryagbhyam Sutra, often translated as “Vertically and Crosswise,” is an effective method for simplifying multiplication. This technique is particularly useful for multi-digit multiplication, breaking down the process into simpler, more manageable parts. Here’s a clear example to demonstrate how to multiply 23 by 12 using this method:

• Multiply the units digits: 3×2=63 \times 2 = 63×2=6
• Multiply the crosswise pairs of tens and units and sum them: (2×2)+(1×3)=4+3=7(2 \times 2) + (1 \times 3) = 4 + 3 = 7(2×2)+(1×3)=4+3=7
• Multiply the tens digits: 2×1=22 \times 1 = 22×1=2

The results are then combined to form the final product. Start from the right (units): the 6 remains as it is. Add the sum of the cross products to the next left slot, which is 7. Finally, place the result of the tens multiplication in the leftmost position, which gives us 276276276.

Conventional Method:

In traditional long multiplication, each digit of one number is multiplied by each digit of the other number, and the results are layered and added. Multiplying 23 by 12 step-by-step:

• Multiply the units of 23 by each digit of 12: 3×2=63 \times 2 = 63×2=6 and 3×1=33 \times 1 = 33×1=3
• Multiply the tens of 23 by each digit of 12: 2×2=42 \times 2 = 42×2=4 and 2×1=22 \times 1 = 22×1=2

Align and add these products properly:

	2	3
x	1	2
Line up the numbers:
6	(3×2)
+3	0	(3×1, shifted left)
+4	0	(2×2, shifted left)
+2	0	0 (2×1, shifted twice left)
Total	=276

Analysis:

The Vedic method, Urdhva-Tiryagbhyam, reduces the steps involved in the multiplication process and minimizes the potential for computational errors. This method is not only efficient for manual calculations but also enhances mental arithmetic skills, allowing for faster and more accurate computations. This streamlined approach is particularly advantageous in competitive environments where speed and accuracy are paramount. Moreover, practicing this method can significantly improve one’s numerical agility and understanding of mathematical concepts.

Nikhilam Navatashcaramam Dashatah (All from 9 and the Last from 10)

Vedic Method:

The “Nikhilam Navatashcaramam Dashatah” Sutra, which means “all from 9 and the last from 10”, is a classic Vedic Mathematics technique designed to simplify subtraction. This method particularly shines when subtracting from bases such as 10, 100, 1000, etc., by using the principle of complements. For instance, to subtract 87 from 100, you don’t subtract directly but use complements:

• Subtract each digit of 87 from 9, except the last digit, which is subtracted from 10.
• For 87, the calculation would be 9−8=19 – 8 = 19−8=1 and 10−7=310 – 7 = 310−7=3, making the result 13. This method transforms complex subtraction into simpler mathematical steps, significantly reducing the mental effort needed, especially with larger numbers.

Conventional Method:

Traditional subtraction often involves borrowing, which can complicate calculations and increase the chance of errors. Taking the same example of subtracting 87 from 100:

• You would need to borrow since the last digit of 100 (0) is less than 7.
• Convert the 10 (tens place) to 0 and increase the units place to 10, then perform subtraction, resulting in 10−7=310 – 7 = 310−7=3 and 9−8=19 – 8 = 19−8=1, combining them to also get 13. This process, although straightforward, is procedurally heavier and prone to mistakes, particularly when dealing with multiple borrowings or larger numbers.

Analysis:

The Vedic method of “Nikhilam Navatashcaramam Dashatah” offers an efficient, less error-prone approach to subtraction. It simplifies the calculation process by reducing the need for borrowing and converting a traditionally subtractive operation into an additive one with complements. This is highly advantageous in scenarios that demand quick mental calculations, such as competitive exams or everyday financial dealings.

This technique not only speeds up the calculation process but also nurtures an intuitive understanding of numbers, encouraging the practitioner to view numerical operations as flexible and interconnected. The simplicity and effectiveness of this method make it superior for handling numbers close to base values, offering a clear cognitive advantage over traditional methods.

Ekadhikena Purvena (By One More than the Previous One)

• Vedic Method: This Sutra is used for squaring numbers ending in 5. For example, to square 25, multiply 2 (the first digit) by 3 (one more than 2) and append 25, resulting in 625.
• Conventional Method: Traditional squaring involves more steps and can be time-consuming.
• Analysis: The Vedic method is straightforward and efficient, making it easy to perform mentally.

This concept has been explained in details in the blog as per given link. So we will not elaborate the principle here.

Critics might argue that without robust statistical analysis and case studies, the effectiveness of Vedic Mathematics could be viewed with skepticism, especially in academic settings that rely heavily on validated educational methods.

Instances like the remarkable mathematical abilities of Shakuntala Devi, known as the “human computer,” illustrate the practical application of these techniques, inspiring interest in Vedic Mathematics. However, these examples alone do not constitute rigorous scientific proof but rather highlight individual achievements that could inspire more formal study.

Moreover, the significant presence of Indian-origin engineers and IT professionals in the United States, who excel in analytics and complex problem-solving and often share a background in Vedic Mathematics, suggests a potential advantage in logical and speedy processing skills. This observation, while suggestive, calls for structured research to validate whether early exposure to Vedic Mathematics can consistently enhance mathematical and cognitive abilities across broader populations.

In a global context, where the efficacy of educational techniques is often gauged through quantitative research and controlled trials, the Vedic approach’s reliance on open and transparent knowledge sharing stands in contrast to more commercially driven research methodologies prevalent in the West. This cultural difference in approach towards intellectual property, such as the commercialization of traditional knowledge like Ayurvedic principles, reflects divergent values in knowledge dissemination and utilization.

To build a convincing case for the widespread adoption of Vedic Mathematics, future research could benefit from collaborative studies that not only measure immediate skill enhancement but also track long-term retention and application of these skills in diverse professional and academic settings. Such studies would provide the needed empirical support to substantiate the claims of Vedic Mathematics’ benefits, paving the way for its integration into mainstream educational systems.
