To know the chosen number

There are steps that must be followed:

1 - Choose - a number between one and fifty and write it on a piece of paper, then fold this paper without your friend seeing it.

2- Ask your friend to choose a number between fifty and one hundred without telling you about it.

3- Ask your friend to subtract the number you wrote on the paper from 99

4- Ask him to add the result with the number he chose.

5 - Ask him to add the hundreds digit with the number consisting of the ones and tens digits.

6- Ask him to subtract the result from his number. Then your friend will be surprised to see that the result of this subtraction is the same number that you wrote on the paper

Here are two examples of that.

If you choose 35, for example, and your friend chooses 60, for example

The mathematical operations are

64 = 35 - 99

124 = 60 + 64

25 = 1 + 24

35 = 25 - 60

This is the number you choose

Here is another example: If you choose the number 23, for example, and your friend chooses the number 74, for example

The operations become as follows

76 = 23 - 99

150 = 76 + 74

51 = 1 + 50

23 = 51 - 74

This is the number you chose

To see the number chosen by others

1- Ask one of your friends to think of a number less than ten, without telling you about it.

2 - Ask him to double this number, that is: to multiply it by two.

3- Ask him to add the number 12 to the result of the previous multiplication

4 - Ask him to subtract from the result he got after dividing by 2 and subtract the number he chose first.

5 - Then tell him that the number that remains with him after subtraction is the number 6.

Here are two examples of that:

If your friend chooses the number 5, for example, he will follow the following operations

10 = 2 × 5

11 = 22 ÷ 2

6 = 11 - 5

If he chooses the number seven, he follows the following mathematical operations:

14 = 2 x 7

26=14 + 12

13 = 2 ÷ 26

6 = 7 - 13

Thus, in the end, he will remain with the number six, regardless of the number he chose. It is noted that this number is half of the number 12, which he increased after multiplying the number he chose by two.

Therefore, you can replace this number with another number, such as asking him to add the number 16, for example, instead of the number 12, and follow the same previous mathematical operations.

In this case, the number 8 remains with him at the end, which is half of 16.

Here is the proof: If he chooses the number 9, for example, he follows the following mathematical operations

18 = 9 × 2

34 = 18 + 16

17 = 2 ÷ 34

8 = 9 - 17

If you replace the number 16 with the number 30, for example. He will remain with the number 15, which is half of the thirty

Here is the proof: If he chooses the number 5, for example, he will follow the following mathematical steps:

10 = 2 × 5

40 = 30 + 10

20 = 2 ÷ 40

15 = 5 - 20

And to see what others choose

1 - Ask one of your friends to choose a number without telling you.

2- Ask him to multiply the number he chose by 3.

3- Ask him to add the number 1 to the product.

4- Ask him to multiply the result by 3.

5- Ask him to add the chosen number to the result.

6- Ask him for the final answer. Delete the ones from it, so what remains is the chosen number.

Here are examples:

1 - Suppose your friend chose the number 4. The calculations are as follows

12 = 3 × 4

13 = 1 + 12

39 = 3 x 13

43 = 4 + 39

Suppose he chooses the number 7

The calculations are as follows:

21 = 3 x 7

22 = 1 + 21

66 = 3 x 22

73 = 7 + 66

We delete the first number, leaving the number 7

Suppose he chose the number 12, then the calculations would be as follows:

36 = 3 x 12

37 = 1 x 36

111 = 3 x 37

123 = 12 + 111

We delete the first number, and the number 12 remains.

- Knowing a specific number that others choose: If you want to amaze your friends, ask one of them to:

1- He chooses a number without telling you about it.

2 - Subtract 1 from it.

3- Double the remaining number.

4 - Subtract 1 from the remaining number.

5- He adds to the remaining number the number he chose.

6- Ask him to tell you about the result.

- Add the number 3 to the result in your secret.
- Divide the resultant (addition) by 3, and it becomes the chosen number. Here is the arithmetic proof:

Suppose the chosen number is 9

8 = 1 - 9

16 = 2 × 8

15 = 1 - 16

24 = 3 + 15

27 = 3 + 24

9 = 3 ÷ 27

The number 9 is the chosen number

Suppose the chosen number is 6 0

5 = 1 - 6

10 = 2 × 5

9 = 1 - 10

15 = 6 + 9

18 = 3 + 15

6 = 3 ÷ 18

The number 6 is the chosen number.

Suppose the chosen number is 12.

11 = 1 - 12

22 = 2 × 11

21 = 1 - 22

33 = 12 + 21

36 = 3 + 33

12 = 3 ÷ 36

It is the chosen number, i.e. the number 12.

Knowing how many others choose

Ask one of your friends to choose a number from 1 to 104 without telling you about it. Then tell him that you know this number if he performs the following mathematical operations:

1 - Ask him to divide the number by 3 and tell you about the remainder if there is anyone left.

2- Ask him to divide the number by 5 and tell you about the remainder if there is anyone left.

3- Ask him to divide the number by 7 and tell you about the remainder, if there is anyone left.

4 - Secretly multiply the remainder by 3 by 70.

5 - Secretly multiply the remainder of the division by 5 by 21.

6 - Secretly multiply the remainder of the division by 7 by 15.

7- Add the products.

8 - Divide the products by 105 and the remainder is the chosen number.

If the total is less than 105, the total is the chosen number

Here's the proof:

Suppose the chosen number is 18

6 = 3 ÷ 18 and the remainder is zero
