It's some number game where you pick a number and + 5 and - 10 and + another number then subtract your original number and it tells you your answer.

I think I figured out how it works...
example:
original # is 15
add 6
add 12
minus 16
add 15
subtract original number
(all it is doing is 6+12-16+15) right? yeah cause I did it skipping the first and last step and it still works...
if you didn't subtract original # there is no way they would be able to get it right. But all they are doing is the math between your two #'s you chose right?
still kinda cool.

Yea,

If you dont think of an original number and dont subtract it you get the same number they have.



But its cool to try and trick people with. HEHE

 

they lost! I picked 10. I ended up with 50 I think, and they ended up with 52.

 

bah.. too much math!

where's my calculator?

 

Does not work with negative numbers...

 

Brings back memories.
First math class on negative numbers.

-7-(-7)=?

 

are you sure your math wasnt wrong? all they are doing is throwing numbers out, and adding them and subtracting them... then whatever they get they say the answer is.

 

maybe my math was wrong, but at least I get to laugh at them

 

thats cool.
