Humph!!!
Think of a number..............
x
Add Ten..................
x + 10
Double the result.............
[x + 10] x 2
Subtract 6................
([x + 10] x 2) - 6
Divide by 2....................
[([x + 10] x 2) - 6]/2
Take away the first number you thought of.........
([([ x + 10 ] x 2) - 6]/2) - X
.
.
.
=([([ x + 10 ] x 2) - 6]/2) - X
=([2x + 20 - 6]/2) - X
=([x + 10] - 3) - x
=x +7 -x
=7

How to get an answer other than 7?
Simple. Make a mistake. (but only 1. If you make 2 mistakes, they might cancel each other out, and you'll accidently get the correct answer.)
