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
