ok, i was a major math nerd in school, so here goes.

it's actually ridiculously simple. there are a very, VERY limited number of possibilities here. let's look at the number 27. in "27", "7" is in the "one's place", and "2" is in the "ten's place". you follow? ok. for any number that you pick...any number at all, when you subtract the number that is in the "one's place" from the original number, you're left with a number that is a multiple of 10. and then the number in the "ten's place" will be the same, whether you chose 21 or 27, so the outcome will be the same. get it? the only possible outcomes are 9, 18, 27, 36...well, you get the idea. multiples of 9!

now, if you look at the chart, you'll notice that all of the multiples of 9 have the same item listed.

and that's how it works.

ta-da!

It's easy. No matter what number you pick, you end up with the number 9. I tried it a second time and that's how it works. 13-4= 9, 12-3= 9, etc.

that is so creepy, she keeps getting it right......how does it work? its gonna drive me nuts lol

I kept doing this over and over again. She kept getting it right. This is spooky.

i did it 3 times and she was right every time, how she do it,

I did it a couple times and the first few I think I didn't do the subtracting but, I read the directions again and, woila, she guessed it right everytime! I picked 23 and 27 (his n my b-days) n both times it was for 18. That is too funny!

i did it 3 time how does she do it

I'm NOT regifting a bottle of wine!!!!Seriously that was great.

OMG!!! I did this two times and it was correct!! How do they do this kind of stuff!!
