This is an old one but it's very thought prevoking...very fun to figure out. Watch, think, and predict. You'll figure it out.
Magic strikes awe as long as you DON'T know how it works. If you can't figure it out, ask me and I will ruin the magic for you in a private note.
It didn't work. I chose 88, so 8+8=16 and that symbol didn't come up. When I look at 88 and 16, I do notice that they have the same symbol.
88-16=72, you have to subtract the sum. The only way it won't work is if you mess up the math. It took me a while to figure it out.
Actually it's pretty simple. You don't need to be a rocket scientist like Bill Roberts to figure it out. If you've had junior high school math, that's sufficient.

Hah! I guess I forgot a step!
It works now, faultlessly reading my feeble mind 
OK, I'm not a rocket scientist and my junior high math seems to have evaproated along the way. HOW THE H... DOES IT WORK!!!!?????? I even looked at the signs without doing the equation, and most of the times it worked! is this a fluke?
Someone please emil me with the answer!
