MIND TEASER

Hey guys, Check out this Mind Teaser!! Its INSANE

i did it multiple times trying to figure out how it knows, but still cant figure it out. it was right all 5 times i did it. freakin mindteaser is teasing my mind!

any 2 digit number that begins with 1 and the 2nd digit added to it and subtracted from the original ALL ends with 9.

any 2 digit number that begins with 2 and the 2nd digit added to it and subtracted from the original ALL ends with 18.

any 2 digit number that begins with 3 and the 2nd digit added to it and subtracted from the original ALL ends with 27.

so on and so on in multiples of 9.

hence why the multiples of 9 all have the same symbols when it comes time for it to 'pick' which number you have

i knew it had to do with multiples of 9 being there were only 9 differant symbols.

mark should be working for NASA or something!

Yea, that one's easy to figure out. It's even easier on other versions that have been out where the table of symbols doesn't dissappear so you can look at the table and study forever. You'll notice every multiple of 9 has the same symbol, so no matter what number you pick that symbol is going to come up. They just shuffle the symbols on the table each time you play, that's why it will come up with different symbols each time. But mathematically it's easy to see how it works, as Mark posted.

lol...not bad tho
