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
:doh: Waste of time
same thing if you take out the double and divide by 2 just halve the number you subtract
Think of a number
add 10
Subtract 3
take away origional number
Answer 7 :doh:
Ashore, I can see your logic.
But what about the subtract 6 bit?
(I understand the algerbra bit of Ivan)
I keep coming up with 111. :~
Oh... hang on... my calculator is in binary mode...
Because you don't double you only subtract half of 6 being 3 :2tsup:
Right Ashore, I am not going to play poker with you.:)
Think of a number
Subtract the same number
Add 7
Do you get 7? :laughing1:
Love your work Ivan:2tsup:
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.)

Answer......
I got -7 by starting with a negative number less than -10 (as in -11, -12, -13)
Do I win a prize?:)
