How to do multiplication ?
Suppose you have to multiply 92 to 93, find their difference from 100, put them like this :
92 -8 93 -7
now subtract 7 from 92 = 85 (or 8 from 92, it is cross subtraction) the base is 100 so answer has
to be in 4 digits
9992 * 9932?
Again put it as base 10000 9992 - 8
deduct 8 from 9932 = 9924 now multiply 8 to 68 = 544 the answer has to be in 8 digits :
How to find squares of numbers
ending in 5?
Suppose you have to find squar of 95, just multiply 9 to hits higher digit and put 25 at the
9*10 = 90, dont forget 25 =9025
similarly, find square of 185,
How to multiply 43 to 47 ?
Here the unit digits are 3 and 7, when you add them, it is 10. so understand a simple trick for
such cases :
multiply 4 to next digit = 4*5 = 20 now multiply both the unit digits : = 21
How to multiply 58 to 52?8+2 = 10 so 5*6 = 30 8 * 2 = 16 so answer : 3016
How to multiply 123 and 321 in
one go ?
Assume 123 as ABC and 321 as EFG respectively.
The simple (but long) formula is : AE / (AF+EB) / (AG+BF+CE)/(BG+CF)/(CG)
=3 / 8 /14 / 8 / 3 (here 14 is two digit, so add 1 of this to 8 – the earlier digit)
How will you square up 109 ?
109 = 100 + 9
so add one more 9 to it :
118 now take square of 9 and append it. = 11881
How will you square 1011?
Add 11 again : 1011 + 11 = 1022 square 11 and append it :
How will you square 53?
50 + 3 = 53 so add 3 more to it :
56 now divide it by 2, we get 28 now append square of 3 to it.
Note: here we have divided by 2, because 100/2 = 50
How will you multiply 303?
303 + 3 = 306
now multiply it by 3 = 918 now append square of 3 to it:
Note : here we have multiplied by 3 because 100 * 3 = 300 (the base is 100)
How will you multiply 411?
411 + 11 = 422
now multiply it by 4 : 1688
now append square of 11 : 168921 answer.
Note : we have multiplied by 4 because 100 * 4 = 400
How will you find square of 257?
257 + 7 = 264
now you divide by 4, 66
append square of 7 (base 1000) = 66049
How will you square up 126?
We know that 1000/8 = 125, so take 125 as base
126 + 1 = 127
divide 127 by 8 : 15.875 now append square of 1 :
How will you multiply 29 to 99?
Instead of 29, werite 28
now deduct 29 from 100, we get : 71 so answer should be : 2871
What to do ?
Prepare for competitive examinations from your schooling onwards – it will help you
increase your mathematics speed, verbal ability (word power and grammar), reasoning skill etc.
Later you may appear in a variety of aptitude tests – and there is a possibility that you will
get good score in these tests. Read good
articles and prepare yourself. There are many books on vedic mathematics, prepare from
Is there any fixed syllabus for
competitive examinations /
aptitude tests ?
No – it is a test of your mind power – your ability to take decision, your overall ability on
the basis of your studies from schooling to date. So there is no fixed syllabus. The best idea can be that you may go through last few
years' papers and identify your strengths and weaknesses and prepare your strategy.
