Introduction: Mind Reading Trick With Numbers

This trick uses simple math to read your mark's mind. This is a great trick for kids, since doing it a few times for an adult would likely give it away.

You will need:
- A brain
- the ability to do simple addition and subtraction

Step 1: Step 1

You will ask your target to think of a number. It can be any number , but forewarn them that picking complicated numbers(decimals, fractions) will yield complicated math problems.

Step 2: Step 2

In Step 2 you ask your target to multiply the number they picked by 2.

Step 3: Step 3

In Step 3 you will ask your target to add 10 to their current total.

Step 4: Step 4

In Step 4 you will ask them to divide their current total by 2. If they've got themselves into a mess at this point, just start over.

Step 5: Step 5

We're almost there. In Step 5 ask them to subtract the original number they picked from their current total.

Step 6: Step 6 Finally!

In the final step you politely tell them the number they have in their mind right now is 5.

Step 7: The Trick

This trick is extremely simple in that you have total control on the outcome.

The secret lies in Step 3 where you ask them to add a number.

You can pick any number divisible by 2 to be added. The final answer will always be the number you asked them to add in Step 3 divided by 2. In this case I asked you to add 10 to your total, hence your final answer was 5.

Good luck and have fun with this.

Hey guys! So I've known this trick for a while, and I've always known that the answer is always half the number you added, but why is this?

noob question;;;;

let I chose a number as x;

2(x) == multiply my 2

2x+10 == add 10

(2x+10)/5 = x+5 == divide by 5

x+5-x == subtract a number I chose at first i.e x

5 == remaining is 5 ; f@ck1ng question

FINALLY, SUBTRACT THE TOTAL FROM THE FIRST NUMBER YOU PICKED.

what this actually means is (FIRST NUMBER)-(TOTAL).

what your supposed to do is (TOTAL)-(FIRST NUMBER).

I do this trick with my 8th graders. It works a little better if you say to add 14, so that the final answer is 7. They don't seem to make the connection, whereas they do make the connection with 10 and 5. They won't know exactly how you did it but they seem to figure it out with 10 and 5.

mrpesas (author)2009-02-19

Technically it should be "Subtract the First number from your Total" If you Subtract the Total from the First number you will get a -5 (negative five).
