How to adjust 8 times 8 to make it 1000
Friends,
In this puzzle 8 is to be adjusted in such a way ,it should repeat 8 times and result should be 1000.You can apply addition,subtraction,multiplication,division means to say you can apply any operation to get the result.
Then have you any idea ok ready to get solution...........
we can put zeroes at empty space add apply addition operation:-
8 8 8
0 8 8
0 0 8
0 0 8
0 0 8
_______
1 0 0 0
_______

Friends,
there is also a interesting result.Take any three digit numbers.

step:1 let us take 450.
step:2 Take reverse of it.
054
step:3 Now subtract 054 from 450
450-054=396
step:4 Now reverse 396
693
step:5 Add 396,and 693
ans is=1089 You can compute another number for all these steps you get exactly the same result1089
Now for verification you can take another example:
step 1: Take a number 345.
step 2: Take reverse of it.
543
step:3 subtract 345 from 543
543-345=198
step:4 Take reverse of 198
891
step:5 Add 198 and 891
ans is=1089
Interesting hai na..........

A Maths Trick for multiplication of two numbers

This article is about a mathematical trick for multiplying two numbers specially for two digits numbers.By this trick you can solve a multiplication sum without copy and pen.

Hello friends,
As you today is fast computing world ,In a new generation students have opportunity to learn fast computing through abacus,which is good to learn upto 14 years students.But we are crossing that age then how we can stand with them ? The only option is by using tricks of mathematics. In previous article A smart maths trick i discuss multiplication any number by 5,99,11 means number is fix but in this trick there need not take a fix number. You can multiply any number two digits or three digits, but it is good for two digits.

No need to take notebook for multiplication

Logic of trick

1. Let us take two ,two digits numbers

let it be 47 and 34

2. Take first number and multiply its digits and take carry separate

4*7=28 carry 2

3. Add carry +first digit of first number*last digit of second number and take carry

2+4*4+3*7=39 carry 3

4. Add carry+multiply digits of second number and don't take carry but take complete resultant number

3+3*4=15=15

5. The answer is=collect complete number from last step and last digit from all another steps

The answer is=1598

Friends,
This is the trick ,i hope you were enjoy it.I will publish new and interesting tricks soon stay in contact............Upto then bye..........Thanks for visit.

Smart Mathematical tricks

This article is about some Mathematical tricks.As today is a very fast computing world.Every exam like Banking,T.E.T(Teaching Eligibility Test,I.A.S etc. all needs speed in computing for selecting in exam.So a person should have some mathematical tricks for faster computing.Here I am try to give to all of you some tricks Which can help you for a good future.

1. Multiplying with 5

Let us take a number 5887.We have to multiply it with 5
Eg. 5887*5=Just divide it to by 2.After divide we get a number=2943,last may add 0
which give 2943.5,ignore remainder the Ans is=29435


2. Any 2 digit number multiply by 99

Eg.let a 2 digit number is 44.We have to multiply it with 99
44*99=(44-1)(100-44)=4356


3. Multiplying any number by 11

Let us take a number 42.We have to multiply it by 11
42*11=(4+2)=6
now add into 42
The answer is=462

4. The square of any number having last digit 5

Let us take a number 85.We have compute its square
85*85= Firstly compute square of last digit which always 25
then multiply all digit remains with its successor.
85*85=8*(8+1)25=7225
