the thing that makes it always 4 is the 8 in your question......
if it was diffrent then the answer would be half of the number you gave us... :)

because the answer is always 4?

You are a genius ??

Think of a number - x

double it - 2x

add 8 - 2x + 8

halve it - x + 4

take away first number = x

left with 4

because when u'v halfed the number and taken away the original number half of 8 is 4 if that makes any sense lol

the number is 10

it's just pure math
(2a +8)/ 2 - a = a +4 -a =4

cause ur a wich

it is the only answer.

its deductive math babe...simple

because the answer is 4?

u said....double it....then u say half it...so that gets rid of those two....then u say add 8....then take away the first number....

soo...16*2=32+8=40/2=20-16=4..wait...n...

I'm left with 7. Maybe I am confused! But it was cool trying to figure it out!

it's basically just taking half of eight. The first number is taken away after doubling and halfing again.

Not that I need the points but this is a simply mathematical problem.

2+2=4+8=12-6=6-2=4

Not difficult to explain, is it?

I am not fooled; I know this trick!

badgers is sooooooooo smart.... call me badgers lol you can be my tutor! lol

Always four

I started with 16, ended up with zero. That's not 4!

I THINK YOU ARE THE NEXT HITLER ON EARTH.........!!

Because all you really do is take half of 8. You think of a number and double it, then later half it and take away the original number. So that leaves you with 0. But of course you have to add 8 in the middle, and then half that, which is 4.

insanity runs in the family

i 4 t every body knew.lol

u guessed, its gotta be right for somebody, right?

7
14
22
11
4

wow. that got me stunned.

my bf did that to me and i thought he could read my mind but then he showed me how to do it so u dont fool me!!!

because half of 8 is 4 and you add on 8 near the start
oh i dunno

you are smart as well as being very HOT lol
