Please think of a number. Add one to this number, then subtract the number you were thinking of minus one. The answer is two! Put simply: (x+1)-(x-1) ...it is the question that drives us. Please Register or Log in to view the hidden image!

Okay. Is there a way to alter the equation to discover what number the person is thinking of...? Please Register or Log in to view the hidden image!

This is what physics and math have devolved into in today's educational system, at least here in the US. Except that most HS kids nowadays couldn't write down the descriptive "a = (x + 1) - (x - 1)", much less solve it. Please Register or Log in to view the hidden image!

Are you serious? There are lots of variants of this. But they all come down to subtracting the number thought of, somewhere along the line so as to confuse the victim, so that all that remains is due to the extra numbers provided by the questioner. P.S. Oh sorry, I see from your cesspooled thread today that you are a nutcase. I'll leave you in peace. [click]
