freaky formula.. for math geeks?

Question

I have this awesome math formula that is guaranteed to work every single time.

Pick a #.
Double it
Double it.
Add 12.
Divide by 2.
Subtract the # that you first thought of.
You always get the answer 6! Every single time!

Try 1 for example.
1 x 2=2
2+12=14
14/2=7
7-1=6

Try any numbers that you can think of and use the formula and you will always get the answer 6. I think that it is cool.

FOLLOW THE FORMULA!

Pick a #
double it.
Add 12.
Divide by 2
Subtract the first number that you thought of from the answer that you got by dividing by 2
You get the answer 6 every time that you use the formula correctly..

K.C, look:
5x2=10
10+12=22
22/2=11
11-5=6.

I didn't literally mean for you to double the number twice! I just put double it wtice to make it look cool. Sorry it confused you.

DON'T DOUBLE TWICE. I just put "double it" twice to make it look cool! Sorry for the confusion.

Answer 1

Got to love math

Answer 2

Will I didnt get 6

I chose 2

2 x 2=4
4 x 2=8
8+12=20
20/2=10
10-2=8

Answer 3

Ok, I pick -1 as my number.


-1
double it:-2
double it again: -4
add 12:8
divide by 2:4
Subtract -1: 5




Guaranteed huh? I want my 45 seconds back.


Oh you're not supposed to double twice.

Trying again with -1.

-1
-1*2 = -2
-2 + 12 = 10
10/2 =5
5 - -1 =6

That works better.

It works with imaginary numbers too.

Answer 4

try the number 10...
for example...

10
10x2=20
20x2=40
40+12=52
52/2=26
26-10=16

Answer 5

2x2=4
4x2=8
8+12=20
20/2=10
10-2=8????
that didnt work so well

Answer 6

not with the number 5 because you have a remander in the division area

Answer 7

When you use the second formula it works otherwise the first method does not work.

Answer 8

i tried 100 and got 106

Answer 9

n
2n
2n + 12

n + 6

answer is always 6

Answer 10
