Mind Reading is a very mysterious test, a mind reading test, accurate every time, what principle

First of all, you need to know that if you choose a two-digit number from 10 99, the difference between the original number minus the sum of the ten digits and the single digit of this number is a multiple of 9. i.e. from 10 to 99 these numbers are calculated according to the above method and there are only a few fixed answers

And any two-digit number you calculate must result in any of them.

Now let's take a look at the number pattern table in the web page, and take a look at the corresponding graphics of the above numbers, and you will find that the corresponding graphics are the same.

At this point, you click on the crystal ball, and the shape displayed in the crystal ball is the corresponding figure of the above number.

So why is the answer a different graph every time?

Because these digital graphs are also changing, they just make you think they are the same. No matter how it changes, the graphics corresponding to these numbers are the same. The last graphic you click on the crystal ball is the one that corresponds to these numbers.

The pattern of these numbers is the same, and it will be rearranged every time you try again, but always keep the pattern of these numbers the same, i.e. a multiple of 9) and the pattern displayed by 9 are the same. You just have to look at the pattern of 9 or multiples of 9. What pattern the ball will show is very simple math.

Observe more!

"Mind reading" is a mathematical process below, not an immortal technique. In the "mind reading" design, if this number is 10a+b, then there is 10a+b-a-b=9a, and all multiples of 9 are a graph, and this is the diagram that appears in the crystal ball.

1. If you have a number in mind, it is a single digit A and a ten-digit number B (A 10B). Such as 25, 5, 2, 10.

2: According to the requirements of the number of centricities, you have to add a and b:

a+b) e.g. 2 5 7

3. Then subtract and add the original number to the result:

a＋10b－（a＋b）＝9b。Such as 25, 7, 18, 2, 9.

4. As you can see from the above, no matter what number you choose, according to the algorithm of mind telling, it will be a multiple of 9 in the end!

5. If you look at the symbols on the right side of the page, are all the symbols after multiples of 9, such as 9, 18, 27, etc., the same? By the way, those symbols are all the same.

The image inside the crystal ball, when the computer program designed, ensures that it is the same as the symbol behind the number of multiples of 9 outside.

6. So, when you point to a little water polo, you will come up with a picture behind the multiple number of 9 outside, and you think it is what you think in your heart.

7. Pay attention to a problem, that is, after you click the crystal ball once, the computer program will make the picture in the ball change, and at the same time, the figure behind all the multiples of nine outside will also become the same picture as the picture inside the crystal ball.

8. If you order again, it's still ......

Note: **It's constantly changing, it's different every time, for example, if you calculate once it's equal to 54, then see that all multiples of 9 are the same as 54. For example, 9 18 27 36 45 54 63 72 81

Haha,It's just a fun math game.。。

The principle of mind reading.

Recently, there is a flash called mind reading on the Internet, which claims to be able to read what you think in your heart, and the rules of the game are as follows:

Choose one or two digits arbitrarily (or alternatively, choose any number from 0 to 99), add the tens of the number to the single digit, and subtract the sum from the number of any choice. For example, if you choose a number of 23, then 2+3=5, then 23-5=18.

Find the graph in the chart that corresponds to the final number, keep it in mind, and click on the crystal ball. You will notice that the shape displayed by the crystal ball is the one you just wrote down in your mind.

In fact, there was an HTML version of this game a long time ago, and now it has only been replaced with a flash version, and the whole secret of the game lies in two points, one of which is a special calculation method; The second is this symbol lookup table.

The first point can be explained by simple algebra, any two-digit number can be shortened to 10*a+b, where (a and b are single digits), for example, 23 in the example is 10*2+3. Then subtract the sum of the single digits from this number, which is expressed algebraically as 10*a+b-(a+b), and merge the same kind of terms, and the result is 9*a, that is, no matter what any two digits you come up with, after calculating according to his method, the result is 9*a, which means that the result can only be a multiple of 9 ......81。Therefore, in flash, it is enough to ensure that the symbols represented by these numbers are consistent.

But some people say that if this is the case, the result of each query will be different. The secret lies in this lookup table, which is actually different every time, and has secretly changed unconsciously. Some people claim that this is a gypsy mind-reading, but because the table is constantly changing, the game cannot be played in the traditional way unless it is done through a computer.

This is also the computer-specific mind reading technique.

Did you find out that this is a sequence?

That is, let's say the ten digits are x and the single digits are y

Then 10x+y-x-y=9x

So, as long as it's a multiple of nine, it's the same pattern, because as long as you do the math according to this formula, you fit that rule

Because the number you choose is designed by it, ensure that the pattern of these numbers is the same, and display the pattern represented by these numbers on the crystal ball, it becomes "mind reading", as follows:

Suppose a two-digit number is arbitrarily selected, the single digit is x, and the ten-digit number is y, then this arbitrary number is 10y+x

Now the arbitrarily selected number minus the sum of the single digits and the ten digits, that is, 10y+x-x-y=9y, which is a multiple of 9.

Since the arbitrarily selected number is a two-digit number, the value of y can only be 1, 2, 3, 4, 5, 6, 7, 8, 9Then you will end up with one of 9, 18, 27, 36, 45, 54, 63, 72, 81.

Just make sure that the numbers (9, 18, 27, 36, 45, 54, 63, 72, 81) are the same in the chart and display the graph in the crystal ball. If you look closely, although the corresponding graphs in the chart change from time to time, the corresponding graphs for 9, 18, 27, 36, 45, 54, 63, 72, and 81 are always the same. That's why you're trying and being fooled.

It's just a basic little strategy for magic.

Did you annihilate this mind-reading technique invented by the legendary gypsies? If yes, then the principle is very simple, I once guessed with my sister, plus and minus but found that the ** of the luck quietly rushed was both of me who came up with it, so I carefully observed it, you start from 1, each luck hunger ten numbers counted, you will find a total of these numbers, you observe the pattern of these numbers, you will find that they are the same, therefore, no matter which number you guess, each time the figure is fixed.
