I asked this as a question above, but thought it might be fun here- just as a link.

Not sure if anyone has already given it here.

I've seen something like that before(a person made a thread months ago about one). It's a math formula of some sort, not sure what though.

The formula has to do with the values of 9 and 18. Here are some examples:

Value of 9:

5973-3759=2214 Lets circle the 1 and write down the other numbers, 224 add these numbers up 2+2+4 = 8 now subtract 9-8=1 which is the circled number.

Value of 18:

8562-6825=1737 Lets circle the 3 and write down the other numbers, 177 add these numbers up 1+7+7 =15 now subtract 18-15=3 which is the circled number.



Try some of your own examples and it will work every time unless you make a math error...
