key to this magic trick is a bit of ALGEBRA.
Let's take a look at the steps one at a time
Pick a whole number from one to 10.
(Here I don't know what you picked so I
call it "x".)
Double this number.
(Now I have two x's or 2x.)
Add 4 to this number.
(So now I have 2x + 4.)
Now divide by 2.
(Here the whole thing (2x + 4) gets divided
Half of two x's is one x , and half of 4 is
So now I'm left with x + 2.)
Finally, subtract your original number.
(I have x + 2, and I take away the original
(x + 2 - x = 2)
It really doesn't matter what you start with, because
I am subtracting it off right here. That will always
leave me with 2.)
Here is what the straight math looks like:
(2x + 4) - x =
2x + 4 - x
1x + 2 - x =
(1x - x) + 2 =
0 + 2 = 2
Make your own mind
reading magic trick. The final answer
does not have to equal 2.
Be sure to include at least
Write out your
directions as you would say them
to an audience.
Then also write out an
ALGEBRAIC explanation of why it
Good Luck! I can't wait
for you to READ MY MIND!
