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.
