Ready to discover the magic? Let's begin!
The Magic Challenge
Think of a number in your head. Don't tell anyone what it is!
Now follow these steps carefully.
Step 1: Choose any whole number.
Step 2: Multiply your number by 2.
Step 3: Add 10 to your result.
Step 4: Divide the new number by 2.
Step 5: Subtract the original number you first chose.
Stop here!
Keep your final answer in your mind.
The Big Reveal!
Your final answer is...
5!
Did the trick work?
If you followed every step correctly, your answer should be 5, no matter which whole number you started with.
Try it again with a completely different number. You will get the same surprising result!
How Does This Magic Trick Work?
It may seem like magic, but there is a clever mathematical secret behind it.
Let's imagine you started with the number 7.
Start with 7.
Multiply by 2: 7 × 2 = 14.
Add 10: 14 + 10 = 24.
Divide by 2: 24 ÷ 2 = 12.
Subtract your original number: 12 − 7 = 5.
The answer is 5!
But why does this work for every starting number?
Imagine your original number is represented by the letter x.
First, you multiply it by 2, giving you 2x. Then you add 10, giving you 2x + 10.
Dividing by 2 gives you x + 5. Finally, subtracting your original number x leaves exactly 5.
The original number disappears from the calculation, leaving the same answer every time.
That's the secret behind this little piece of mathematical magic!
Try This Trick on a Friend
Now that you know the secret, you can become the magician.
Ask a friend to choose a number silently. Guide them through the five steps without revealing the final result.
When they finish, confidently announce that their answer is 5.
For extra fun, ask them to write their final answer on a piece of paper before you reveal it. You can even pretend to concentrate deeply, as if you are reading their mind.
Remember, the fun comes from the presentation. A simple calculation can become a memorable magic trick when you perform it with confidence and a little mystery.
Bonus Challenge: Can You Change the Magic Number?
Here is a puzzle for curious minds.
What happens if you change Step 3 and tell your friend to add 20 instead of 10?
Keep all the other steps exactly the same.
Will the final answer be 5, 10, 20, or something else?
Think about it before reading the explanation.
Answer: The final answer will be 10!
Adding 20 and then dividing by 2 creates an extra 10. Subtracting the original number still removes the starting number, leaving 10.
You can experiment with different numbers to create your own variations of this trick.
