Page 5: magic of math

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

Page 6: magic of math

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.

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

Page 13: magic of math

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

Page 15: magic of math
Page 16: magic of math

Multiply your number with two

Add the result with five

Multiply the result with five

Add four to the result

Page 17: magic of math

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

Page 18: magic of math

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

Page 19: magic of math

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
