For audience :
1.Please choise one of
the numbers on the
box A, B, C , D and E
2.Then we will addition
it very quickly

trik1. Additon last digits at box A, B, C, D, and E
2. then reduces by 50
Example
Audience chooses number 69 ( A's column), 147 ( Column b), 186( Column c), 377( Column d) and 459( Column e).
By use of trik upon you adequately add terkahir's number of to five that number, namely 9 + 7 + 6 + 7 + 9 = 38. Then, reduce 50 by 38 = 12, Sandingkan is number second that, result 1238. So, 69 + 147 + 186 + 377 + 459 = 1238.

I need your
participation
![Page 10: magic of math](https://reader033.vdocuments.site/reader033/viewer/2022052301/559ad4bf1a28abf3078b463e/html5/thumbnails/10.jpg)
Follow My Instructions
1. Think a number that you want
2. Multiply your number with 3
3. Then addition it by 1.
4.Last, Multiply it with 3.

YOUR NUMBER
your number must be
the results you get,
then eliminated the
number 3 on last digit.

The Secret
Translation of math like this, for example,
numbers to be searched = A, then:
Formula = ((A x 3) + 1) x 3) + A
Formula = ((A x 3 x 3) + 3) + A
Formula = (A x 9) + 3 + A
Formula = A x (9 + 3 / A + 1)
Formula = A x (10 + 3 / A)
Formula = A x 10 + 3

So in fact the secret number is
multiplied by 10 and added
only 3, so if number 3 is
eliminated will stay number
(which is actually just multiplied
by 10).

Magic 3

Multiply your number with two
Add the result with five
Multiply the result with five
Add four to the result

I will guess the number you’ve chosen! .......

The secret The formula:
Y (the number that have chosen by participant) x 2 + 5 x 5 + 4
The last digit of the result is always 9
The original number is all digits in front of nine minus 2

For example A participant choose 1676766
1676766 x 2 = 3353532
3353532 + 5 = 3353537
3353537 x 5 = 16767685
16767685 + 4 = 16767689
The secret : 1676768 – 2 = 1676766
