Have you felt that squaring a number is the tedious process? Well, not at least for numbers ending with 5. Here I present a simple trick which helps you calculate the squares of 2 digit and 3 digit numbers ending with 5 within seconds. Let's get into the trick!!

Let's start with easy number 15 all of you know the square of 15 is 225.

Here 15 has two digits which are 1 and 5

There are three simple steps in this trick

**Step 1:**

Add 1 to number apart from last digit 5 here it is 1.

1+1=2

**Step 2:**

Now multiply 1 with the result 2

1*2=2

**Step 3:**

Now we know 5^{2 }=25

Just attach the number obtained in step 2 with 25 which is 225

And it's done!

For clear understanding let's take another example

75

**Step 1: **

7+1=8

**Step 2:**

7*8=56

**Step 3:**

Attach 56 with 25 which is 5625

752 =5625

Very Simple right and you can use this principle for all numbers ending with 5

Let's take a 3 digit number 105

**Step 1:**

10+1=11

**Step 2:**

10*11=110

**Step 3:**

Attach 110 with 25 which is 11025

105^{2}=11025

I hope the concept is clear by now, Ask me if you have doubts.

Happy Learning!

Multiply faster using "Vedic Ganit" technique

Ritesh

I will explain a simple and fastest process of multiplication. This can help you to get answers faster. Let's assume you have to multiply 9999 X 2456. Now think how much time it will take? Maybe 30 sec. or 50 sec. or more as well.. Now try this: 9999 x 2456 --------------- 24557544 ... read more

I will explain a simple and fastest process of multiplication. This can help you to get answers faster.

Let's assume you have to multiply 9999 X 2456.

Now think how much time it will take? Maybe 30 sec. or 50 sec. or more as well..

Now try this:

9999

x 2456

---------------

24557544

I didn't use any calculator. let me explain the steps.

Step 1. Subtract 6 (last number) from 10 = 4 (10-6)

Step 2. Rest numbers you can subtract from 9, so (9-5) , (9-4) , (9-2) = 4 , 5 , 7

Step 3. Now subtract 1 from 2456 = 2457

Step 4. You got the answer. i.e **2457 754 4**

This is just a small example and this will only work if you have one multiplier with 9's only. I know you won't get always similar but for other, there is a different rule. I hope i will get another quick lesson for that. Or reach me to learn this types of tricks which can make your life easy.

Subtraction Of Numbers In An Easy Method

As we know in decimal system ten digits are used. I.e 0 - 9. Subtracting a number from base 10, 100, 1000. An easy way to calculate is just subtracting all digits of a digit from 9 and last digit by 10.For an example, subtracting 56 from 100: 100 - 56 = (9 - 5) | (10 - 6) = 44Let's check it using... read more

As we know in decimal system ten digits are used. I.e 0 - 9. Subtracting a number from base 10, 100, 1000. An easy way to calculate is just subtracting all digits of a digit from 9 and last digit by 10.

For an example, subtracting 56 from 100:

100 - 56 = (9 - 5) | (10 - 6) = 44

Let's check it using our conventional method, in units place it is 6 there. So carry from tens place, there also 0, so so take carry from hundred places, I.e in units place has value 10 so subtracting 6 from 10 we get 4 and now in tens place there is digit 9. Now subtract 5 from 9 we get 9 - 5 = 4. So our answer is 44. So lengthy using carry.

If we use the first method we have to do just only subtract 9 from all digits and last digit from 10. This is one of the powerful sutra "All From 9 And Last From 10" Of Vedic Mathematics. We also know that complement of 56 is 44. As if we add 56 with 44 we get 100.

Next, try for subtracting 65 from 10000:

10000 - 65 = 10000 - 0065 = 9935.

Vedic Mathematics is a very powerful tool for us to get quick calculations

For Multiplication of two 2-digited numbers, we can follow FOIL technique.

If you want to multiply 74×36(let's present it as ab×cd)

Find 7×3×100=2100 (a×c×100)----------multiply First to first digits-----F

Find (4×3+ 7×6)×10=540 [(bc+ad)×10]----------multiply outside and inside digits and multiply their sum with 10-----OI

Find 4×6=24 ( b×d) -------multiply last to last----------L

Add all 2100 + 540 + 24 ____________ 2664

That's the product.

Vedic Mathematics for Multiplication of two 2-digited special numbers

Naimish

In case of two 2-digited numbers whose digits in 10's place are same and sum of the digits in unit places is 10 For example:- 38 and 32 (10's place digits are equal and 8+2=10) 38×32 can be found very easily 3×(3+1)×100=1200 (the number in 10's place × next number tio it×100 8×2... read more

In case of two 2-digited numbers whose digits in 10's place are same and sum of the digits in unit places is 10

For example:- 38 and 32 (10's place digits are equal and 8+2=10)

38×32 can be found very easily

3×(3+1)×100=1200 (the number in 10's place × next number tio it×100

8×2 =16 (product of digits in unit places) add the result and get the product

38×32=1200+25=1225

That's the result.

Abacus is limited. Vedic maths is unlimited. Abacus is more about addition subtraction. Whereas Vedic maths trains you in everything like addition subtraction, multiplication division, squares, square root, cube root..so on.. Vedic mathematics can be taught to the kid as small as 8 yrs old..
