Mathematics is formed by many constant principles. If you follow the rules correctly, you will always find the same result every time. However, the use of math in magic tricks is like a form of performing art in science. Of course, you can’t completely read people’s minds with these tricks, but if done right, you’ll surprise your friends by guessing their correct answer without being revealed!

Find someone willing to join the magic trick. Find the person you want to impress and they have time to do your magic, too. It’s best to find a quiet place to work because distractions will make things confusing.

Ask them to choose an integer from 1 to 10. In theory, they can choose any number. However, you’d better limit it to 1 to 10 for simplicity. Larger numbers make the calculation more complicated; The same goes for choosing decimals or fractions. [1] X Research Source

Impress with the game “The answer is 3”. This game is suitable for beginners because it is very simple. However, you still have enough grounds to impress others, so just follow these steps and make the other person not understand why you know the result:
Ask the person to multiply the selected number by 2.
Next is to multiply the current result by 5.
Then divide the number you just found by the number you chose initially.
Finally, subtract the current number by 7.
Now it’s time to “guess” the answer! If you have followed the above steps correctly, the answer will always be 3.
So what is the truth behind the veil of secrecy?
- For example, if the person chooses the number 3, the calculation will look like this: 3×2=6. 6×5=30. 30/3=10. 10-7=3.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/29/Read-Someone%27s-Mind-With-Math-%28Math-Trick%29-Step-4-Version-4 .jpg/v4-728px-Read-Someone%27s-Mind-With-Math-%28Math-Trick%29-Step-4-Version-4.jpg”,”bigUrl”:”https://www.wikihow.jpg” com/images/thumb/2/29/Read-Someone%27s-Mind-With-Math-%28Math-Trick%29-Step-4-Version-4.jpg/v4-728px-Read-Someone%27s-Mind -With-Math-%28Math-Trick%29-Step-4-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing” :”<div class=”mw-parser-output”></div>”}
Play the game “Divide in two”. This game is a bit more complicated, but is a perfect way to impress your friends. This time, you will also choose a number; so have an even number ready in mind before proceeding. Once the other person has chosen a number, you will perform the following steps:
Ask the person to multiply the selected number by 2.
You will choose an even number for yourself. The opposite person will add the current number with the original selected number.
Next, they will divide the result by 2.
Finally, subtract the original number from the current number.
“Guess” the result. This time, the correct answer will be half of the even number you chose.
- For example, if you choose 10 and the other person chooses 3, the math will work like this: 3×2=6. 6+10=16. 16/2=8. 8-3=5. Half of 10 is also 5!
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/4b/Read-Someone%27s-Mind-With-Math-%28Math-Trick%29-Step-5-Version-3 .jpg/v4-728px-Read-Someone%27s-Mind-With-Math-%28Math-Trick%29-Step-5-Version-3.jpg”,”bigUrl”:”https://www.wikihow.jpg” com/images/thumb/4/4b/Read-Someone%27s-Mind-With-Math-%28Math-Trick%29-Step-5-Version-3.jpg/v4-728px-Read-Someone%27s-Mind -With-Math-%28Math-Trick%29-Step-5-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing” :”<div class=”mw-parser-output”></div>”}
Impress your friends with the game “Lucky 13”. This is a very interesting game that is made based on the property of multiplying 9. It is important that the number chosen by the other person is between 1 and 10. Once the other person has chosen the number, you will proceed as follows: :
Ask the person to multiply the selected number by 9.
Then add the first and second digits of the result together. If it’s a single-digit number (such as 9), they add that number to 0.
Add the number you found by 4.
It’s time to “guess” the answer. The result will always be 13.
Others will begin to wonder why the results are the way they are.
- If the person chooses the number 3, the calculation will be as follows: 3×9=27. 2+7=9. 9+4=13.

Add effects to your performance. [2] X Research Source While it is most important to follow the steps correctly, the fact that you are performing magic and magic also requires style. Perform confidently and dramaticly to the delight of others.
- You don’t have to wear a magician’s outfit, but this outfit will make you look like you’re magical.

Some parts of a magic trick are often a distraction. [3] X Research Source Most magic tricks distract the audience with unnecessary steps and information. The main motive of the games in this article is to make the opponent have to perform the calculation to subtract the number they have chosen. Once the variables are gone, you can control the math.

Determine the characteristics and frequency of occurrence in mathematics. The reason that the “Lucky 13” magic trick works is because the multiplication of 9 by the numbers 1-10 is done in a special uniform way. In this case, each answer (like 9, 18, 27, etc.) is equal to 9 when you add the two digits together. Although this feature only appears in the multiplication of 9, it makes for an interesting magic trick, especially when the opponent can quickly realize the fact that the other magic tricks cancel the selected number. initial.

Remember that each answer involves a constant in the calculation. [5] X Research Source You are free to add as many additions or subtractions as you want, as long as you can eliminate the variable that the opposite person has chosen. For example, the game “Answer by 3” can be arranged to result in any number.

Try creating your own magic trick. Once you’ve gotten used to the math mind-reading game, you probably have the idea to create your own magic trick. Although you can create a complex game, it is better to just start with the simple ones and then gradually increase the level. Beginners should use the “Answer equals 3” game as a template and change the constant value to create a new math operation. From there, you can come up with innovative new ways to suppress variables.

- Don’t forget to try to improve your performance. People want to be entertained and how you distract them with your ingenuity is just as important as the magic trick itself!
Advice
- If you’re performing in front of young children, it’s better to have a computer ready. Children can have trouble doing math operations mentally and giving them the wrong answer can ruin the whole performance.
- True magicians don’t usually reveal their secrets, but if your friends insist on knowing the truth, you can guide them through this article!
- Don’t repeat the same game with the same person.
Warning
- You should not perform mind readings of many people at the same time. Not only is this confusing, but it also ruins the fun of mind-reading.
