A Math Mind Trick
All you need to do this is yourself, and maybe a calculator if you're not good at math
PICK A NUMBER from 10 to 100 (but don't tell anybody what it is!)
then DOUBLE IT.
Now ADD 12.
then DIVIDE BY 2.
Finally... SUBTRACT YOUR ORIGINAL NUMBER. (do you still remember it?)
And here's the weird part:
YOUR ANSWER IS 6. (Creepy, isn't it?)
Math Limerick
A dozen, a gross and a score,
Plus three times the square root of four,
Divided by seven,
Plus five times eleven,
Equals nine squared and not a bit more!
12 + 144 + 20 + 3(sqr(4)) 2
------------------------- + 5(11) = 9 + 0
7
