OOOh amazing, thanks you!!

[ArgoRuben642]

obv you can pick any number!

when you subtract it in the end is doesnt matter :S

[swamagic2525]

hey its quite obvious but the answer is not always correct.its true for real numbers only and not for complex numbers.this is not a trick

[sadizes]

you honestly think some one would pick a complex number when you asked them to pick a number.

I think you are the only one who would be like. Hey this didn't work cause i picked 9i!

[nickolayer]

Excuse me, but that's basic algebra.

Let's say we take x as the number, then we go:

x

x+5

2(x+5)=2x+10

2x+10=2x+6

(2x+6)/2=x+3

x+3-x=3

Obviously, you get to three all the time, because your number doesn't really change anything.

i choose four and it didnt work...

[WellyBootFish]

Hmmm.. FAIL :L

I think he lies!

[mrdaddyofyou]

yeah about that.. you made a mistake coz look

4+5=9

9x2=18

18-4=14

14/2=7

7-4=3

tadaaaaa the answer is 3

@mariokart4life

4+5=9

9*2=18

18-4=14

14/2=7

7-4=3

Stupid it works because of the subtract your starting number....... that means you always really start on 0. Then when you add 5 you get 5 then double to get 10 then minus 4 gives 6 then half it gives you 3. Phhhfft.

cartooon10001 he said add 5 in the beggining not 4 ;)

[cartooon10001]

hey!!!! try to choose the no. 5 5+4=9 double it becomes 18 then subtract 4 =14 then divide by 2 so it becomes 7 then subtract again the no. u choose which is 5!!!!! therefore.... 5+4=9 9x2=18 18-4=14 14/2=7 7-5= 2!!!!!!!!!! to told us it would be 3!!!!!! but the ans. is two(2) dos,

[moiststing]

add 5 :P

[AquaCarb]

You can choose 5 but you must add 5, not 4.

[nazmieski]

u do it wrong. if u choose the no. 5

then u have to add with 5. not 4.

5+5=10

10 x 2=20

20-4=16

16/2=8

8-5=3

Neat....I tried it and it works.

[hhhtwins]

Waste of time. What exactly does this achieve?

Not useful in anyway. Sorry man, you've wasted my time.

[jwm239]

...variations are possible depending on

what numbers one initially adds or multiplies

by. The '22' trick involves taking any 3-

digit number whose digits are different,

adding the digits (giving sum S), and

finally adding all six possible 2-digit

numbers of the original 3-digit number

and dividing that sum by S. Quotient is

always 22.

omg thats amazing im about to do it!!!!=)=p
