This is the second mind reading trick in this blog. The first one was titled “**The Answer is 3!**”

**The Mind Reading Trick**

Step 1: Think of a number.

For example, we think of 8.

Step 2: Multiply it by 3.

Now, 8 multiplied by 3 equals 24.

Step 3: Add 12.

12 + 24 = 36

Step 4: Divide by 3.

36/3 = 12

Step 5: Subtract the original number. The answer is 4.

12 – 8 = 4.

Note that whatever number you chose in Step 1, the final answer after step 5 will always be 4. If you don’t believe me try other numbers. 🙂

** The Secret Behind the Trick**

Like the previous mind reading trick, the secret behind this trick can be revealed using simple Algebra. If we let* n* be the number, then we can think of the steps above in terms of *n*.

Step 1: Think of a number.

This time let’s think of our number as *n*.

Step 2: Multiply it by 3.

The product of 3 and *n* is 3*n*.

Step 3: Add 12.

The sum of 3*n* and 12 is 3*n* + 12.

Step 4: Divide by 3.

Dividing 3*n* + 12 by 3 results to *n* + 4.

Step 5: Subtract the original number. The answer is 4.

Since the original number is *n*,

*n* + 4 – *n* = 4.

That is the secret behind the mind reading trick above.
