The vertical and crosswise (VC) method is a core component of Vedic multiplication, and understanding its application is crucial for efficiently solving a wide range of numerical problems.
Vertical Multiplication The vertical multiplication step involves multiplying the ones digits of the two numbers. This straightforward calculation provides the initial part of the solution.
For example, in the multiplication of 23 and 45, the vertical multiplication step would be:
 3 × 5 = 15
Crosswise Multiplication The crosswise multiplication step involves multiplying the ones digit of the first number with the tens digit of the second number, and the ones digit of the second number with the tens digit of the first number. These two products are then added together.
Continuing the example of 23 and 45:
 3 × 40 = 120
 5 × 20 = 100
 Crosswise product: 120 + 100 = 220
Combining the Results The final step is to add the vertical and crosswise products to obtain the complete solution.
 Vertical product: 15
 Crosswise product: 220
 Total product: 15 + 220 = 235
Therefore, the product of 23 and 45 using the Vedic VC method is 1,035.
The Vedic VC method offers several advantages over the traditional "carry and multiply" algorithm:

 (20 + 7) × (30 + 8)
 = (20 × 30) + (20 × 8) + (7 × 30) + (7 × 8)
Step 3: Perform the Vedic VC method on each component.
 20 × 30 = 600 (Vertical: 0 × 0 = 0, Crosswise: 2 × 3 = 600)
 20 × 8 = 160 (Vertical: 0 × 8 = 0, Crosswise: 2 × 8 = 160)
 7 × 30 = 210 (Vertical: 7 × 0 = 0, Crosswise: 7 × 3 = 210)
 7 × 8 = 56 (Vertical: 7 × 8 = 56)

 45 = 40 + 5
 73 = 70 + 3
 (40 + 5) × (70 + 3)
 = (40 × 70) + (40 × 3) + (5 × 70) + (5 × 3)
 = 2,800 + 120 + 350 + 15
 = 3,285
Therefore, the product of 45 and 73 using the Vedic approach with the distributive property is 3,285.
Key Takeaways:

2.5: Multiplication of ThreeDigit Numbers
In this subchapter, we will explore the Vedic approach to multiplying threedigit numbers, building upon the foundations established in the previous sections.
The Vedic multiplication of threedigit numbers follows a similar logic to the techniques used for twodigit numbers, but with an expanded application of the vertical and crosswise methods.
Let's consider an example to illustrate the process:
Multiply 234 and 567 using the Vedic method.
Step 1: Decompose the numbers into place values.
 234 = 200 + 30 + 4
 567 = 500 + 60 + 7
Step 2: Apply the Vedic VC method to each place value combination.
 Vertical: 4 × 7 = 28
 Crosswise:
 4 × 60 = 240
 7 × 30 = 210
 4 × 500 = 2,000
 234 × 7 = 1,638
 Add the crosswise products: 240 + 210 + 2,000 + 1,638 = 4,088
Step 3: Add the vertical and crosswise products.
 28 + 4,088 = 4,116
Therefore, the product of 234 and 567 using the Vedic approach is 132,578.
The key aspects of Vedic multiplication for threedigit numbers are:

Decomposition: Breaking down the threedigit numbers into their place values (hundreds, tens, and ones) is the first crucial step, as it allows for the systematic application of the Vedic VC method.

Expanded Crosswise Method: The crosswise multiplication step becomes more complex, as it involves combining the products of various place value combinations (ones with hundreds, tens with ones, etc.). Careful organization and attention to detail are essential in this phase.

Additive Nature: The final solution is obtained by adding the vertical and crosswise products, maintaining the integrity of the place values throughout the calculation process.
Let's consider another example to further reinforce the Vedic multiplication of threedigit numbers.
Multiply 456 and 789 using the Vedic method.
 456 = 400 + 50 + 6
 789 = 700 + 80 + 9
 Vertical: 6 × 9 = 54
 Crosswise:
 6 × 80 = 480
 9 × 50 = 450
 6 × 700 = 4,200
 456 × 9 = 4,104
 Add the crosswise products: 480 + 450 + 4,200 + 4,104 = 9,234
 Total product: 54 + 9,234 = 9,288
Therefore, the product of 456 and 789 using the Vedic approach is 360,184.
Key Takeaways:
 The Vedic multiplication of threedigit numbers follows a similar logic to the twodigit case, but with an expanded application of the vertical and crosswise methods.
