Vedic Math's Tricks for Fast Calculation
Have you ever struggled with long calculations? Do you wish you could solve math problems faster? Vedic Math's is here to help! In this blog post, we'll explore some amazing Vedic Math's tricks that can make you a math whiz. Let's dive in!
What is Vedic Math's?
Vedic Math's, also known as Vedic Mathematics, is an ancient Indian system of mathematics. It consists of simple and easy techniques to solve complex math problems quickly. These techniques are called sutras. Let's learn some of these powerful tricks.
10 Vedic Math Tricks for 10X Faster Calculation
In addition to the tricks above, here are two more to make it a total of 10 tricks for even faster calculations
1. Multiplying by 11
To multiply any two-digit number by 11, just follow these steps:
Example: 23 x 11
Separate the digits: 2 and 3
Add the digits: 2 + 3 = 5
Place the result in the middle: 253
Steps | Example |
Separate | 2 and 3 |
Add | 2 + 3 = 5 |
Result | 253 |
2. Squaring Numbers Ending in 5
To square a number ending in 5:
Example: 25²
Remove the 5 and multiply the remaining number by its next higher number: 2 x 3 = 6
Append 25 to the result: 625
Steps | Example |
Multiply | 2 x 3 = 6 |
Append 25 | 625 |
3. Multiplying Numbers Near 100
For numbers close to 100, use this trick:
Example: 98 x 97
Subtract each from 100: 2 and 3
Multiply the results: 2 x 3 = 6
Subtract the sum from 100: 100 - (2 + 3) = 95
Combine the results: 9506
Steps | Example |
Subtract | 100 - 98 = 2, 100 - 97 = 3 |
Multiply | 2 x 3 = 6 |
Subtract | 100 - (2 + 3) = 95 |
Result | 9506 |
4. Doubling and Halving
To multiply two numbers, double one number and halve the other:
Example: 16 x 25
Double 16: 32
Halve 25: 12.5
Multiply: 32 x 12.5 = 400
Steps | Example |
Double | 16 -> 32 |
Halve | 25 -> 12.5 |
Multiply | 32 x 12.5 = 400 |
5. Multiplying by 9
To multiply any number by 9:
Example: 7 x 9
Multiply by 10: 7 x 10 = 70
Subtract the original number: 70 - 7 = 63
Steps | Example |
Multiply | 7 x 10 = 70 |
Subtract | 70 - 7 = 63 |
6. Addition of Large Numbers
To add large numbers, break them down:
Example: 487 + 658
Round each number: 490 + 660
Add: 490 + 660 = 1150
Adjust: 1150 - 3 - 2 = 1145
Steps | Example |
Round | 490 + 660 |
Add | 1150 |
Adjust | 1150 - 3 - 2 = 1145 |
7. Subtracting from 1000
For quick subtraction from 1000:
Example: 1000 - 357
Subtract each digit from 9 and the last from 10: 1000 - 357 = 643
Steps | Example |
Subtract | 1000 - 357 = 643 |
8. Multiplying by 5
To multiply any number by 5:
Example: 18 x 5
Multiply by 10 and halve: 18 x 10 = 180, 180 / 2 = 90
Steps | Example |
Multiply | 18 x 10 = 180 |
Halve | 180 / 2 = 90 |
9. Divisibility by 3
To check if a number is divisible by 3, sum the digits and see if the result is divisible by 3:
Example: Is 123 divisible by 3?
Sum the digits: 1 + 2 + 3 = 6
Check: 6 is divisible by 3, so 123 is too.
Steps | Example |
Sum | 1 + 2 + 3 = 6 |
Check | 6 ÷ 3 = 2 |
10. Multiplying Numbers Close to 10
For numbers near 10, use this trick:
Example: 9 x 8
Subtract each from 10: 1 and 2
Subtract one number from 10: 10 - 1 = 9
Multiply the results: 1 x 2 = 2
Combine: 9 - 2 = 7 (combine for final step)
Steps | Example |
Subtract | 10 - 9 = 1, 10 - 8 = 2 |
Subtract | 10 - 1 = 9 |
Multiply | 1 x 2 = 2 |
Combine | 9 - 2 = 7 |
Conclusion
Vedic Math's is a powerful tool that can make calculations much faster and easier. By using these simple tricks, you can improve your math skills and solve problems in a fraction of the time. Start practicing these tricks today and watch your math abilities soar!
