  3. Division: Vedic Mathematics provides methods for quick and efficient division, such as the Paravartya Yojayet (Transpose and Adjust) method, which involves transposing and adjusting digits to simplify the process.

Multiplication Techniques in Vedic Mathematics

Urdhva-Tiryagbhyam (Vertically and Crosswise)

The Urdhva-Tiryagbhyam sutra, meaning “Vertically and crosswise,” is one of the most powerful techniques in Vedic Mathematics. It simplifies the multiplication of large numbers by breaking them into smaller parts and multiplying them in a specific pattern.

For example, to multiply 23 by 45:

  1. Multiply the units digits: 3 × 5 = 15 (write down 5, carry over 1).
  2. Cross-multiply and add the results: (2 × 5) + (3 × 4) + 1 (carry over) = 10 + 12 + 1 = 23 (write down 3, carry over 2).
  3. Multiply the tens digits: 2 × 4 = 8, add the carry-over 2 = 10.

So, 23 × 45 = 1035. This method is much quicker than traditional multiplication and reduces the risk of errors.

Nikhilam Sutra (All from 9 and the Last from 10)

The Nikhilam Sutra simplifies multiplication, especially when numbers are close to a base power of 10 (like 10, 100, 1000). It works by taking the complements of the numbers with respect to the nearest base and then multiplying these complements.

For example, to multiply 97 by 96:

  1. Find the complements of 97 and 96 with respect to 100: 3 and 4, respectively.
  2. Multiply the complements: 3 × 4 = 12.
  3. Subtract one number’s complement from the other number: 97 – 4 = 93 (or 96 – 3 = 93).

So, 97 × 96 = 9312. This method is efficient and easy to perform mentally.

Division Techniques in Vedic Mathematics

Paravartya Yojayet (Transpose and Adjust)

The Paravartya Yojayet sutra, meaning “Transpose and adjust,” is used for division. This method involves transposing the divisor and adjusting the dividend accordingly to simplify the division process.

For example, to divide 256 by 12:

  1. Transpose the divisor: 12 becomes -2 (as a single digit from the right).
  2. Adjust the dividend: 25 and 6.
  3. Perform the division: 25 – 2(6) = 25 – 12 = 13. Then, 13 and 6 divided by 12 gives the quotient 21 and remainder 4.

This method is particularly useful for long division and provides a clear, step-by-step approach.

Digital Roots Method

The Digital Roots method, also known as casting out nines, is another efficient technique for division. It involves finding the digital roots of both the dividend and the divisor to simplify the calculation.

For example, to divide 256 by 4:

  1. Find the digital root of 256: 2 + 5 + 6 = 13, and 1 + 3 = 4.
  2. Find the digital root of 4: 4.
  3. Divide the digital roots: 4 ÷ 4 = 1.

So, 256 ÷ 4 = 64 (the traditional division confirms this). This method is quick and helps in verifying the accuracy of calculations.

Addition and Subtraction in Vedic Mathematics

Specific Sutras for Addition

Vedic Mathematics offers specific sutras that simplify the process of addition. These sutras focus on breaking down numbers into smaller parts and adding them systematically to avoid errors.

  1. Break down the numbers into smaller parts.
  2. Add each part separately.
  3. Combine the results for the final sum.

This method is particularly useful for adding large numbers mentally and ensures accuracy.

Techniques for Efficient Subtraction

Subtraction in Vedic Mathematics is simplified using the Nikhilam sutra, which involves taking complements and adjusting the numbers accordingly.

For example, to subtract 487 from 723:

  1. Find the complement of 487 with respect to 1000: 513.
  2. Add this complement to 723: 723 + 513 = 1236.
  3. Adjust for the base: 1236 – 1000 = 236.

So, 723 – 487 = 236. This technique reduces the number of steps and minimizes errors.

Squaring Numbers Quickly

Duplex Method for Squaring

The Duplex method is a quick and efficient technique for squaring numbers. It involves breaking down the number into smaller parts, squaring each part, and combining the results.

For example, to square 37:

  1. Square the units digit: 7 × 7 = 49 (write down 9, carry over 4).
  2. Multiply the digits and double the result: 3 × 7 × 2 = 42, add the carry-over 4 = 46 (write down 6, carry over 4).
  3. Square the tens digit: 3 × 3 = 9, add the carry-over 4 = 13.

So, 37² = 1369. This method is much quicker than traditional squaring methods and can be performed mentally.

Base Method for Squaring

The Base method is another efficient technique for squaring numbers close to a base power of 10. It involves finding the difference from the base, squaring the difference, and adjusting the number accordingly.

For example, to square 96:

  1. Find the difference from the base: 96 – 100 = -4.
  2. Square the difference: (-4)² = 16.
  3. Adjust the number: 96 – 4 = 92.

So, 96² = 9216. This method simplifies the process and reduces the risk of errors.
