Think of any number between 1 and 10, and multiply it by 9. If the answer is more than two digits, add the two digits and subtract 5. The answer is your lucky number. (This is to calculate 4)

Single performance is actually not the category of mind magic ~ Let me give you an example.

1。 Danish elephant:

Are you ready to travel around the world? Fasten your seat belt! The plane will be bumpy.

Count from 1 to 10, okay?

Multiply by 9. If the answer exceeds two digits, add the two digits and subtract 5, and the answer is your lucky number.

Now I want you to convert this number into the corresponding letters in the alphabet. For example, if the number is 1, it will be associated with A, if it is 2, it will be associated with B, 3 will be associated with C, 4 will be associated with D, and so on.

Ok, Lenovo starts with this letter, and this is where we are going;

Imagine the spelling in this country. What's its second letter? Then think of a large animal that begins with these two letters. Then, its color. . .

oh . Sorry, there are no gray elephants in Denmark.

Mathematical principle: 9 is a multiple of 1 to 10, and the sum of numbers is 9, (9, 18, 27, 36 ...), minus 5 is 4, corresponding to D.

It is easy for westerners to think of Denmark and Denmark, which start with D. Elephants are obviously large animals, and 99.9% of the elephants in his mind are gray.
