My Math Trick As A Kid

5 June 2009 One Comment

mathI remember when I was a kid probably 2nd or 3rd grade my Uncle Henry pulled this trick on me using simple math.  It astonished me so much that I was determined to figure out just how it worked.  Being a natural math nerd also played into my motivation and I eventually discovered the solution to the elementary mind reading.  What is the trick you might ask…  Let me give you a basic example and I am sure it will be very obvious.  Again, it is not to astonish an adult but you might remember similar tricks or maybe this very trick from your childhood and I invite you to share your thoughts or memories.

The Trick

Think of a number any number?  If you are not good with mental math then I suggest you pick a lower number.

Now add eight to that number… Subtract three… Add four… Subtract two… Add twelve… now subtract the original number you thought of…

The number is… 19

I can’t tell you how many kids, not to mention some adults, would beg me to tell them how I knew and I would always look at them and say “I read your mind”.  Yeah yeah, I know I was a nerd.  NEWSFLASH – I still am

Think On…
