Moore Manor Why can the magic crystal ball be guessed, and what is the principle?

It's a math problem.

You see, if you're thinking about 65

65-(6+5)=54 is a multiple of 9.

The principle is as follows: Your tens of digits are a, the single digit is b, and this number is 10*a+b, so the number you calculate according to his algorithm is 10*a+b-(a+b)=9*a, that is, the number you calculate is 9 times the number on the dozens of places you think, right, that is, the number you calculate can only be 9 18 27 36 45 54 63 72 81

And then you look at the graph of these numbers, and it's not the same.

So the number you calculate must be a multiple of 9, and the multiple of 9 is the symbol, and every time you do it, the page will automatically refresh, and the graph will change if you think of the multiple of 9, but it's still the same.

Hello, it's actually quite simple.

As it was said upstairs.

Let me give you a simple example.

For example, a number.

If you were asked to add 10 and subtract 10, would you still get this number?

This is also the principle.

Suppose it is a, then it is 10a [omit the multiplication sign] +b-(a+b), and the same kind of terms are combined to get 9a

So no matter what, it's the same.

What you will learn in junior high school ( o

Damn, I know... It's a trap...

You want a number, like 46

First subtract the single digits: 46-6=40

In other words, it doesn't matter what the single digit is, it will be subtracted immediately.

What about the tens digits? After subtracting the single digits, the resulting number must be one of 10, 20, 30, 40, 50, 60, 70, 80, 90, no problem, right?

It takes a single digit to get 40 by subtracting a single digit from a forty-odd do, and the same goes for the others.

After subtracting 4, you get 36

List all the possible numbers, and that's it

If you look at the patterns of the above numbers, you will find that they are the same.

Although the pattern changes each time the measurement is taken, these numbers are consistent.

Therefore, as long as the crystal ball gives this pattern, it will definitely be correct.

Damn it deceived so many people... I've been deceived for a while...

I finally got it!

is a multiple of nine

The pattern of these numbers is the same (but it will change the pattern every time) the number you choose, after subtracting ten digits and single digits, this number is a multiple of nine.

Whatever you choose is a multiple of nine.

So it (the system) can guess.

Do you understand?

Solution: Let the number you guess be ab.

Then what do you think of the number is.

ab-a-b=10a+b-a-b=9a

a must be a positive integer.

9a is a multiple of 9.

Multiples of 9 are the same as the figures, one at a time.

Example: 54-5-4=45

The result must be a multiple of nine, and if you look closely, the symbol will change every time, but the multiple of nine will never change. Ninety and above are excluded, because it is impossible to subtract ten digits to get more than ninety. Then you don't have to think about it, just remember which symbol nine is, what it looks like, and then it must be a multiple of nine symbol in the end.

It's a 9x relationship, and it's all the same symbol, so no matter how you pick the number, it will guess it, for example: 79-7-9=63;62-6-2=54

As long as you don't have to subtract, just look at a pattern and the answer will be this one, if you look at 2 or 3...There will be one of them.,There's no need to subtract it at all.,But I haven't seen how she got it yet.。。。

I'm also curious... But when I don't think about anything, or think about a number that hasn't been calculated, it goes wrong.

However, I looked at 28 first, and then it occurred to me that if I followed its rules, then it would be impossible to get 28.

Therefore, there should be a lot of numbers that have been eliminated, and the probability of guessing will increase.

But why it's so accurate, I don't know.

I didn't guess what I thought, it should have been Meng. Hehe.

I don't know the principle of Shenma, and I am also a hundred hits.
