1. The document describes three magic tricks involving numbers: predicting a person's home number and age based on a series of mathematical operations with a given result, determining a three-digit number a person selects based on reversing and subtracting the numbers, and predicting the result of operations performed on an even number selected by a person. 2. An example is provided for each trick to demonstrate how the method allows determining secret numbers selected by the audience through a series of steps. 3. The tricks rely on performing standard arithmetic operations on numbers provided by an audience member and then applying logic to deduce the secret numbers from the final results.

3. PREDICT THE NUMBER OF HOME AND
AGE
1. Choose one of the audiences to play with us.
2. Ask he / she to take the number of his / her home
without say it to us and the other audiences.
3. Then times 2 by the number of his / her home.
4. Next, add by 5.
5. After that times by 50.
6. Add with his / her age.
7. Then add by 365.
8. Ask he / she to say the result.
9. From the result we can predict the number of his / her
home and his / her age.

4. PREDICT THE NUMBER OF HOME AND
AGE
Example :
1.Choose one of the audiences to play with us.
2.The number of his home is 42
3.42 x 2 = 84
4.84 + 5 = 89
5.89 x 50 = 4450
6.Add the result by his age (4450 + 27 = 4477)
7.4477 + 365 = 4842
8.Without say to the audiences, to predict the number of his /
her home and his / her age we must subtract the result by 615.
4842 - 615 = 4227
From here we know that the number of his home is 42 and his
old is 27 years old

5. PREDICT THE NUMBER
1. Choose one of the audiences to play with us.
2. Ask he / she to take the number that consist of 3
digits, without say to us and the other audiences.
3. Then, ask he/ she to reverse the number.
4. After that we ask he / she to substract the first
numbers that his / her choose with the number that
she / he reversed. (Note: the large number must be
subtracted by the least number).
5. Then we ask he / she to say the first digit from the
number that detraction result.
6. From here we will know the result.

6. PREDICT THE NUMBER
Example:
1.Choose one of the audiences to play with us.
2.The number that choose by the audience is 328.
3.The audience reverse it (328 >< 823)
4.Then, the audience substract the number that he / she
choose with the number that he / she reversed
(823-328=495).
5.After that we ask he / she to say the first digit from the
number that detraction result (4).
6.From here we know that the result is 495 (because the
middle digit of the number always 9, then the last digit of
the number is the result from subtract 9 by the first digit of
the number ).

7. The Even Number
1. Ask one of the audiences to think an even
number and ask he/she to say it to us and
the other audience.
2. Ask he/she to devide it by 2.
3. Add the result by his/ her even number
4. After that we ask he / she to add the result
by 10

8. The Even Number
Example
1. The even number that choose by the audience is 4 then
ask she to say it.
2. Without say to the audiences we make a predict of the
result from the operations that will we do is 60. (Multiply
the even number by 15 (4x15=60))
3. Then we ask he / she to devide the even number by 2
(4:2=2)
4. Next we ask he / she to add the result by his / her even
number (2+4=6)
5. After that we ask he / she to times by 10 (6 x 10 =60).
6. Then we show our predict to the audiences, her answer is
equal to our predict.
