A 9's clock.......

A 9's Fan's Clock I do not claim a copyright on the picture below. Actaully i found this image on a site. And i was so amazed, so i took it from there to show all of you.  Hence, the picture: The 1 - 12 are calculated each with three 9s (in a not unique way) as (9/9)9 (9 + 9) / 9 √9 + 9 - 9 √9 + 9 / 9 √9! - 9 / 9 9 - 9 / √9 9 - √9 + .9 9 - 9 / 9 9√(99) 9 + 9 / 9 99 / 9 9 + 9 / √9 Isn’t  it amazing, it was a new thing for may be be for you also..........

9's Magic.....

The Magic of Number 9

 

1.Finding the Digital Roots by Casting “9”

What is Digital root?  

If we add up the digits of a number until there is only one number left we have found what is called the digital root.  In other words, the sum of the digits of a number is called its digital root.

            Example:

            For 5674, 5 + 6 + 7 + 4 = 22 and 2 + 2 = 4

            »          4 is the digital root of 5674

One use of digital roots is for divisibility tests (like 3 and 9).  This method makes it easier to calculate the digital root.

Example:

Example:

            Find the digital root of 257520643

  

            Steps:

1. 2 + 7 = 9, cross out 2 and 7.

2.4 + 3 = 9, cross out 4, 3 and 2.

3.There are no other groups of numbers adding up to 9.

4.Add up the remaining digits, 5 + 5 + 0 + 3 = 13.

5.13 is more than 9, so 1 + 3 = 4.

6.The digital root is 4.

If there is nothing left after having cast out nines then the digital root is 9.

2. It will never let you go

Think of a two digit number, say 42, then subtract the reverse of its digits, 24, from 42

Choose any two digits number and for each one reverse the digits and subtract the smaller number from the larger.  Look at all the answers you get.  Do they all have a common divisor?  What do the digits sum to each time?  

Some Examples:

You see how fascinating and enjoying it is. In each case the difference is divisible by 9 (i.e. the common factor is 9) and the sum of the digits of the difference is always 9.

Do you think this will also work for three digit number or four-digit number.  Try it out!

What wee can do with 123456789 only..........

math

Today i come with new fun with maths, is all with only the digits 123456789 see what we can do with them

The problem is to place plus or minus signs between them so that the result of thus described arithmetic operation will be 100.

We got one answer

12 + 3 - 4 + 5 + 67 + 8 + 9 = 100

and suggested there existed at least one more. I do not claim to have made an exhaustive search but there appear to be more than just two answers. One of this is

123 + 4 - 5 + 67 - 89 = 100

I am sure there it at least another one. Want to find it?

There is a keen observation that in the two examples above at least one of the operations is subtraction. And this is also true for all additive (the ones in which the only allowed operations are addition and subtraction) examples below. In fact, it is impossible to avoid subtraction even if the digits come in an arbitrary order. To figure out why, it may be helpful to recollect the notion ofdigital roots.

You may allow for operations other than addition and subtraction. This leads to a completely new set of problems with numbers having fractional parts. Variations include setting targets other than 100. Here, for example, a representation of one that uses all ten digits:

1 = 148/296 + 35/70

There are many ways to merrily spend time solving arithmetic problems. One way is to attempt representing numbers with limited means. For example, I can represent 100 with five threes as100 = 33×3 + 3/3. It's surprising how many numbers could be represented.

In the 1960s another kind of number puzzles have become very popular. Cryptarithms are brain teasers obtained when digits in numerical calculations have been replaced by letters. Customarily, distinct letters stand for different digits. Stars substitute for any digit and are not related to each other.

The problem is to place plus or minus signs between 123456789 so that the result of thus described arithmetic operation will be 100.

Some years ago, il found in the french magazine Science et Vie the 11 solutions:

1 + 2 + 34 - 5 + 67 - 8 + 9 = 100
12 + 3 - 4 + 5 + 67 + 8 + 9 = 100
123 - 4 - 5 - 6 - 7 + 8 - 9 = 100
123 + 4 - 5 + 67 - 89 = 100
123 + 45 - 67 + 8 - 9 = 100
123 - 45 - 67 + 89 = 100
12 - 3 - 4 + 5 - 6 + 7 + 89 = 100
12 + 3 + 4 + 5 - 6 - 7 + 89 = 100
1 + 23 - 4 + 5 + 6 + 78 - 9 = 100
1 + 23 - 4 + 56 + 7 + 8 + 9 = 100
1 + 2 + 3 - 4 + 5 + 6 + 78 + 9 = 100

If we put a "-" before 1, we have one more solution:

-1 + 2-3 + 4 + 5 + 6 + 78 + 9 = 100

Using the "." decimal separation we found another solution:

1 + 2.3 - 4 + 5 + 6.7 + 89 = 100

What about 987654321 ? There are 15 solutions, said Science et Vie:

98 - 76 + 54 + 3 + 21 = 100
9 - 8 + 76 + 54 - 32 + 1 = 100
98 + 7 + 6 - 5 - 4 - 3 + 2 - 1 = 100
98 - 7 - 6 - 5 - 4 + 3 + 21 = 100
9 - 8 + 76 - 5 + 4 + 3 + 21 = 100
98 - 7 + 6 + 5 + 4 - 3 - 2 - 1 = 100
98 + 7 - 6 + 5 - 4 + 3 - 2 - 1 = 100
98 + 7 - 6 + 5 - 4 - 3 + 2 + 1 = 100
98 - 7 + 6 + 5 - 4 + 3 - 2 + 1 = 100
98 - 7 + 6 - 5 + 4 + 3 + 2 - 1 = 100
98 + 7 - 6 - 5 + 4 + 3 - 2 - 1 = 100
98 - 7 - 6 + 5 + 4 + 3 + 2 + 1 = 100
9 + 8 + 76 + 5 + 4 - 3 + 2 - 1 = 100
9 + 8 + 76 + 5 - 4 + 3 + 2 + 1 = 100
9 - 8 + 7 + 65 - 4 + 32 - 1 = 100

Write the sign "-", three solutions:

-9 + 8 + 76 + 5-4 + 3 + 21 = 100
-9 + 8 + 7 + 65 - 4 + 32 + 1 = 100
-9-8 + 76 - 5 + 43 + 2 + 1 = 100

With the decimal point:

9 + 87.6 + 5.4 - 3 + 2 - 1 = 100 (solution of my own)

If I "shuffle" the digits there are many solutions. I found some when I was young, for example:

91 + 7.68 + 5.32 - 4 = 100
98.3 + 6.4 - 5.7 + 2 - 1 = 100
538 + 7 - 429 - 13 = 100
(8×9.125) + 37 - 6 - 4 = 100 etc etc etc ....

very interested by cryptarithms and I collect them. Do you want to receive french cryptarithms ? Do you know non-english cryptarithms ? Thanks

Anthony Lesar notes that the solution 1 + 2 + 3 - 4 + 5 + 6 + 78 + 9 = 100 could be a little modified without changing the result: 1! + 2! + 3 - 4 + 5 + 6 + 78 + 9 = 10

There may be many solutions that we didn’t know still...........

You can try to find them , and it’s not a waste of time, it’s fun and also its increases our  mind capability to solve problem and as well as increases our IQ also.........

So try to find your new ans and post it .........and have fun

Keep Rockking....... \m/

Some more new Magics ....:p

m

        Ok lets try some new one

Take any three digit number in which the first and last number differ by more than one i.e. 335 would be O.K. but not 333, or 332.
Reverse this number
Subtract the smaller number from the larger.
Add this answer to the same number reversed and the answer is ALWAYS 1089.
Example 1:-
335    Reversed = 533
533 - 335 = 198
198 + 891(198 reversed) = 1089
Example 2:
932 reversed = 239
932 - 239 = 693
693 +396 = 1089

     Dice Game

Get a friend to throw a dice three times and you will be able to tell them which numbers came up and in which order.

This is what they have to do -

• Throw dice
• Multiply number by 2
• Add 5
• Multiply by 5 (Remember this total)
• Throw dice second time
• Add this second number to the previous total.
• Multiply by 10 (Remember total)
• Throw the dice for the third time and add the number to the last total.

Ask for the final total.  Subtract 250 and you will be left with three figures.  These figures represent the numbers thrown and the in which they appeared.

Example:

First throw = 4

4 x 2 = 8

8 + 5 = 13

13 x 5 = 65

Second throw = 2

65 + 2 = 67

67 x 10 = 670

Third throw = 6

670 + 6 = 676

676 - 250 = 426 = 4 2 6

Isn’t it surprising or not ?? Yeah its fun.
Ok try it with your friends ... i’l come soon with more tricks

Funs with Figure: Is it Math or Magic?

A lot of us seem to struggle so badly in math. Its like no matter what we do to understand every equation we never get how it's done and we always got the wrong calculations. Math can be very difficult to master.

over 3000 years ago in Ancient India, the Vedics devised a system of mental math based around the way the mind naturally works. Their ways and patterns are quite different to the methods we have today. It is most simple and effective. During 20th century it was rediscovered however it did not became famous and readily accessible to the public.

Examples of these are ways to multiply any 2-digit numbers together in your head within seconds! Like 26 x 38… does that look hard? It's simple when you know this ingenious method of multiplication. How to calculate naturally - from left to right, he easiest method ever for dealing with fractions and a lot, lot more!

Don't worry this is not another copy of your calculus, algebra or statistic book rather a 52 easy-to-follow pages that are presented in plain, simple language that shows you exactly what you need to do, examples and quizzes where you can practise yourself with your new math skills.

For example lets see some magic of maths that can be used by you to make your friends jealous of you and they will proud on you.

Believe it or not, numbers can be fun.  Here are a few examples -

     Sum of Human Knowledge (contributed by Eric Bishop)

If you multiply the number 142,857 by anything between 1 and 6 the answer contains the same digits. 

e.g. 142857 x 3 = 428571      and       142857 x 6 = 857142

If you multiply the same figure by 7 the answer is 999,999.

See its a kind of fun or u can say a magic to your friends. There are many these type of magic or which can be done by us ...... let see

     A game to find out a person's age and how many coins they are carrying.

·         Ask someone to double their age (either mentally or on paper) but, obviously, they must not tell you.

·         Then to add 5 and multiply by 50.

·         Finally, they must add the number of coins they have on them.   If they do not have any, nothing is added.

·         They then tell you the final answer.

·         Now all you have to do is take away 250.  The first two digits of the answer you are left with are the persons age and the last two the number of coins in their possession.

This works unless they are carrying over 100 loose coins.
Example -   25 x 2 = 50 + 5 = 55 x 50 = 2750 + 6 = 2756
                     2756 - 250 = 2506

This is surely u can say a magic if you try this with your friends, they will surely ask you that how did you do that.
