In a world where calculators and smartphones are always within reach, mental math might seem like a lost art. But what if you could solve complex math problems in your head—quickly and accurately—without relying on any gadgets? Enter Vedic Math, an ancient system of mathematics that makes mental calculations not only possible but also incredibly efficient.
One of the most powerful techniques in Vedic Math is the Vertically and Crosswise method, which simplifies multiplication, especially for two-digit numbers. In this article, we’ll explore how this method works, why it’s so effective, and how you can use it to multiply two-digit numbers mentally. Say goodbye to calculators and hello to the joy of mental math!
What is Vedic Math?
Vedic Math is a system of mathematics that originated in ancient India, rooted in the Vedas, which are ancient Indian scriptures. It is based on 16 sutras (formulas) and 13 sub-sutras (corollaries) that provide clever shortcuts and strategies for solving mathematical problems. These techniques are designed to be intuitive, fast, and easy to understand, making them perfect for students, professionals, and anyone looking to improve their math skills.
Unlike traditional methods, which often involve lengthy steps and repetitive calculations, Vedic Math emphasizes simplicity and efficiency. It’s not just about getting the right answer—it’s about getting there quickly and with minimal effort.
Why Mental Math Matters
Mental math is more than just a party trick. It has real-world benefits, including:
Improved problem-solving skills: Mental math trains your brain to think logically and creatively.
Increased confidence: Being able to solve problems quickly boosts your self-esteem.
Time-saving: No need to reach for a calculator or pen and paper.
Enhanced memory: Mental math exercises your brain, improving your overall cognitive function.
With Vedic Math, mental math becomes accessible to everyone, regardless of age or skill level.
The Vertically and Crosswise Method: A Game-Changer for Multiplication
The Vertically and Crosswise method is one of the most versatile techniques in Vedic Math. It simplifies multiplication by breaking it down into smaller, more manageable steps. This method is particularly useful for multiplying two-digit numbers, as it allows you to perform the calculation mentally with ease.
Let’s break it down step by step.
How to Multiply Two-Digit Numbers Using the Vertically and Crosswise Method
Step 1: Write Down the Numbers
Let’s take an example: 23 × 41.
Step 2: Multiply Vertically (Right to Left)
Start by multiplying the digits in the rightmost column (the units place):
3 (from 23) × 1 (from 41) = 3
Write down 3 as the rightmost digit of the answer.
Step 3: Multiply Crosswise and Add
Next, multiply the digits crosswise and add the results:
2 (from 23) × 1 (from 41) = 2
3 (from 23) × 4 (from 41) = 12
Add these two results: 2 + 12 = 14
Write down 4 and carry over 1 to the next step.
Step 4: Multiply Vertically (Left to Right)
Finally, multiply the digits in the leftmost column (the tens place):
2 (from 23) × 4 (from 41) = 8
Add the carryover from the previous step: 8 + 1 = 9
Write down 9 as the leftmost digit of the answer.
Step 5: Combine the Results
Putting it all together, the answer is 943.
Example 1: Multiplying 23 by 41
Let’s verify this with our example:
23 × 41 = 943
That’s it! You’ve just multiplied two two-digit numbers mentally using the Vertically and Crosswise method.
Example 2: Multiplying 34 by 52
Let’s try another example: 34 × 52.
Multiply vertically (right to left):
4 × 2 = 8
Multiply crosswise and add:
3 × 2 = 6
4 × 5 = 20
6 + 20 = 26
Write down 6 and carry over 2.
Multiply vertically (left to right):
3 × 5 = 15
15 + 2 (carryover) = 17
Combine the results: 1768
So, 34 × 52 = 1768.
Example 3: Multiplying 67 by 89
Let’s try one more example: 67 × 89.
Multiply vertically (right to left):
7 × 9 = 63
Write down 3 and carry over 6.
Multiply crosswise and add:
6 × 9 = 54
7 × 8 = 56
54 + 56 = 110
110 + 6 (carryover) = 116
Write down 6 and carry over 11.
Multiply vertically (left to right):
6 × 8 = 48
48 + 11 (carryover) = 59
Combine the results: 5963
So, 67 × 89 = 5963.
Why the Vertically and Crosswise Method Works
The Vertically and Crosswise method works because it breaks down multiplication into smaller, more manageable steps. By handling one pair of digits at a time, you reduce the complexity of the calculation and make it easier to perform mentally. This method also minimizes the need for carrying over, which can be a common source of errors in traditional multiplication.
