**Teaching Mental Maths Tricks to Anyone and Everyone!**Learning to perform fast

**mental maths**calculation will help you immensely irrespective of which field of life you deal with.Knowing these mental maths tricks will give you a positive edge over the others.Whether you are a student,aspiring engineer,statistician,scientist,school teacher or anyone else dealing with numbers,learning this quick mental tricks and techniques

(popularly known as

**Vedic Maths techniques**) is always going to benefit you.
You must have heard of Shakuntala Devi-the lady who performed maths calculations faster than a Computer,you can do it too, just with a little bit of practice.

For example, let say you want to

**multiply 52*11**.This can be calculated in less than 1 second but if you want to do it traditionally,it will take you around 5-6 seconds.Isn't it?
So let see how using a simple mental maths trick,this calculation can be done in a matter of seconds...

To multiply 52 and 11,imagine there is a space between 52

52*11= 5_2 (Put an imaginary space in between)

Now,what to do with that space?

Just add 5 and 2 and put the result in the imaginary space

So, 52 * 11 =5

__7__2 (which is your answer)
Isn't it great?

Lets try some more examples:

1)

**35 * 11 = 3**__(3+5)__5 = 3__8__5
2)

**81 * 11 = 8**__(8+1)__1 = 8__9__1
3)

**72 * 11 = 7**__(7+2)__2 = 7__9__2 etc..
With just a little bit of practice you can easily perform these simple mental maths tricks in the blink of an eye.

People sitting for competitive exams often complain that they could not complete the Question paper within a certain time period as the paper was too length(l)y.But for your information,let me tell you that all papers of all competitive exams are so designed that students can finish it within the given time period.Its just that student do not have the required efficiency.So in tight time constraint situation where time plays a very important role,knowing these quick mental maths techniques will give you an edge over your competitors.It will be your X-Factor.It will give you that sharpness and smartness required to crack any competitive exams.

Lets take an example of this sum which has been taken from the 2010 question paper of a Popular Bank PO Examination (Aptitude Section):

**(Q) Is 456138 divisible by 9?**

Now, it only takes 2 seconds for you to determine the answer.But if you go by the traditional way then it will take you 10 seconds.So you can see the difference.Those 8 extra seconds you win,you can spend on other question.Isn't it?

No let see the solution

**(Answer)**To test whether a certain large number is divisible by 9 or not,'

**just add all the digits of the number and if the end result is divisible by 9,then you can say that the entire large number will be divisible by 9 too**'.

**4+5+6+1+3+8=27**

Now since 27 is divisible by 9 so

**456138 will be divisible by 9**too.
By now you must have some idea, how important it is to know these mental maths tricks.Knowing these simple calculation techniques gives you an advantage over others and can get you a job,get you crack any competitive exams and much more.

**Here are few more mental maths tricks..**

**Multiply any large number by 12 mentally in seconds**

To multiply any number by 12 just double last digit and thereafter double each digit and add it to its neighbour

For example

**21314 * 12 = 255768**
Lets break it into simple steps:

**Step 1:**021314 * 12 = _____8 (Double of Last Digit 4= 8 )

**Step 2:**021314 * 12 = ____68 (Now Double 1= 2, and add it to 4, 2+4=6)

**Step 3:**021314 * 12= ___768 (Now Double 3=6, and add it to 1, 6+1=7)

**Step 4:**021314 * 12= __5768 (Now Double 1=2, and add it to 3, 2+3=5)

**Step 5:**021314 * 12= _55768 (Now Double 2=4, and add it to 1, 4+1=5)

**Step 6:**021314 * 12= 255768 (Now Double 0=0, and add it to 2, 0+2=2)

So your final answer of

**21314 * 12 = 255768**
Another example...

**Calculating Square of numbers quickly...**

Lets

**calculate the square of 54**
So

**(54)^2**= 5^2 +4 -- 4^2 = 25 +4 ----16 =29-------16=**2916**
Similarly

**(55)^2**= 5^2 +5 --5^2=25+5------25=30---------25=**3025**
Similarly

**(56)^2**= 5^2 + 6--6^2=25+6------36= 31--------36=**3136**etc..
Similarly try out squares of 57,58 etc..

These are just few of the many

helpfull for poor people

These tricks are awesome and definitely save lot of time which is very helpful in exam and specially in competitive examination where time saving is very difficult so such tricks are very helpful.

How to do Trigonometry step by step

n1 tricks...

This trick doesn't works all the time. Take example of 39.

Guys this works only for 2 digits in the range of 50-59.. Thats it. It's not a generic logic... So thumbs down for this...

Vedic Maths is fun to learn and hence work... It really makes calculation easy...

I have been taking tutorial for vedic maths online. vedic math techniques are very clearly stated in this online coaching for cat by a very experienced teacher... It is def helping me hopeits helpful for you as well

http://www.wiziq.com/course/9277-lr-vr-di-ds-speed-calculations-quant-general-awareness

First i was very much afraid of maths but now i am enjoying all this. Really awesome techniques. thank u

vedic maths is interesting but i don't think it can help to solve the problem mentally. Example that i know how to calculate 3-digit number multiple with other 3-digit number by vedic formula but it's still hard to do in mind if the problem is just called out, without writting. As i cannot remember the temporary results. Any advice on this issue?

do 64*11?

As i am teaching Vedic Maths since last 7 years to the students above 10 years, it is very important to learn a method properly .....

now to do 64x11=

6 (6+4) 4=

now 6 (10) 4

means add tense place now

(6+1) 0 4

i.e.704

how we will multiply 42x22..as we can see that the addition of the two digits are not expanding to tense so we cant add the the previously added number for eg: 42x22=924

so 4(4+2)2=462 which is wrong according to the multiplication done by mr.prajakta sir after adding the 2 digits the number is expanding to tense place but not in my case so sir i would be glad if you can help me out of this..

thanks

to learn more tricks in easiest way do visit

trick for 12 is nice

Vedic maths is based on sixteen sutra's or principles . These principles are general in nature and can be applied in many ways . In practice, the vedic system is used to solve difficult problems or huge sums in more effective and easy way.These method are just a part of a complete system of mathematics which is far more systematic than the modern system taught now. The simplicity of vedic mathematics helps us to solve the calculations mentally with sifficient practice.

Vedic maths is highly helpful in cracking competitive exams .There are many vedic math online course one of them is http://www.wiziq.com/course/1507-vedic-mathematics-complete-certified-course So if anybody is intrusted to learn vedic math online can visit the link.

good but these are difficult 2 undersand

How's the Square of 69^2

square technique fails for 69.....(69)^2=4762 but as per vedic maths its (69)^2=4581

69*69=(25+19)+19^2=44+361=4761

It's very very easy for small kids and adults

one can also try this

62^2 = 6^2+2...2+2...2^2 = 3844

64^2 = 6^2+4....4+4...4^4 = 4096

Very usdfull info to do fast caluclation competative examx

It would be very easy if you understand the logic properly otherwise it will be just a formula nothing else. Anyway your answer will be like the following:

42*22=?

Answer:=4*2/(4+2)*2/2*2

=8/12/4=8+1/24=924

good book

one more trick in vedic maths is multiplication with nines for eg you got to multiply 57956*99999 this may take you around 2 minutes in conventional method but less than 5 seconds in vedic maths let me explain how subtract one from the side which is not completely of nines(57956) which is 57955 now subtract 57955 from 99999 i.e. 42044 now combine both results 5795542044 and that is the answer

another example 45678*99999

45678-1 = 45677

99999-45677=54322

upon combining 4567754322

you can use this trick for multiplication when one side is full of nines and other side consists of other nos.

it works under the sutra(aphorism)

ekanyunena purvena i.e. one less than before

(we subtracted one)

amazing isn't it it has been used in ancient india for a long time,for more visit

http://blogannath.blogspot.in/2011/01/vedic-mathematics-lesson-56-auxiliary.html

the last trick does not work on other numbers lyk 77,64 n such..

this works only between 50-59.this man is making us a mad head.

last squares trick does not work for 49 69 etc...Please explain

according to Vedic 49*49 = (16+9----81=25---81=2581

But actually it is 49*49=2401

Fine

How will calculate square root of 92 or 79?

how to easily find out the cube root of any no.?

49 x 11 = 539

4+1 3 9 ( 4 + 9 = 13 ) The sum of digits more than 9 , this will work. Test yourself.

Nice to see that blog commenting done right still has many benefits. Thanks for sharing your insights.

Fast Math

Nice article..Here is an adaptive learning platform to practice math online @ http://begalileo.com especially designed for grade I-X digital students.

You can use this formula for taking out square of any number a×a 2 ab b×b like for

42×42=1764 1st do 2×2=4 then 2×4×2=16 write 6 and take 1 as carry now do 4×4 =16 add 1 carry the answer is 1764.
