a cool magic mental trick i know
1) think of a number and dont tell me
2) add 2 to that number
3) add 8 to that number
4) add 5 to that number
5) substract the number that you didn't tell me (the first one that you thought of)
6) is the remaining number 15?
it's simple to figure out when it's written but if you tell it to anybody in real life they'll be like WTF!!!
btw, if you haven't figure it out, i know the answer because the number that you think and you dont tell me, i then tell you to substract it
so if you thought of 10
i told you to add 2 + 8 + 5 = 15
so it's 10 (ur number) + 15
then i tell you to take off ur number (10) and the remain is 15, you do have to remember the numbers you are adding
keep sarging son!
