12 Free Magic Tricks to Amaze Your Friends

Math Magic:

Math isn’t just about solving equations and crunching numbers; it’s also a source of wonder and amazement! Here are 12 math magic tricks that will leave your friends in awe.

1. The Magic Number 1089

Trick: Ask someone to choose any three-digit number where the digits are not all the same. Reverse the digits to create a new number, and subtract the smaller number from the larger one. Then, reverse the result and add it to the original difference. Result: The final answer will always be 1089!

2. The Power of 11

Trick: To multiply any two-digit number by 11, add the two digits together and place the sum between them. Example: ( 36 \times 11 ) becomes ( 3 (3+6) 6 ), which equals 396.

3. The Age Guess

Trick: Ask someone to multiply the first number of their age by 5, add 3, then double the result. Finally, have them add the second number of their age to the result and tell you the answer. Reveal: Subtract 6, and you’ll have their age!

4. The Sixes Prediction

Trick: Write down the number 12345679 (the 8 is missing). Ask someone to choose a number between 1 and 9, multiply your written number by their choice, and then multiply the result by 9. Outcome: The result will be their chosen number repeated in every digit!

5. The Vanishing One

Trick: Write down any number. Underneath it, write the same number in reverse and subtract the smaller from the larger. Cross out one digit from the result (except zero), and you can tell them the sum of the remaining digits! Secret: The sum of the digits will always be 9.

6. The Birthday Paradox

Trick: In a room of just 23 people, there’s a 50% chance that two people share the same birthday. Explanation: This is due to the non-intuitive nature of probability.

7. The Quick Square

Trick: To quickly square a two-digit number ending in 5, multiply the first digit by itself plus one, and put 25 at the end. Example: ( 75^2 ) becomes ( 7 \times 8 ) and 25, which is 5625.

8. The Digit Sum

Trick: Any number divisible by 9 also has digits that add up to 9. Test: 162 is divisible by 9, and ( 1 + 6 + 2 = 9 ).

9. The Multiplying Nines

Trick: For multiplying nines, the product will have digits that add up to 9. Example: ( 9 \times 3 = 27 ), and ( 2 + 7 = 9 ).

10. The 1089 Reverse

Trick: Similar to the first trick, but ask them to reverse the process after obtaining 1089. They’ll end up with their original number!

11. The Missing Card

Trick: Have someone pick a card from a deck and place it back. After shuffling, lay out the cards in 4 rows of 13. The row with a missing suit reveals the chosen card’s suit, and the sum of the ranks in that row equals the rank of the chosen card.

12. The Magic Circle

Trick: Draw a circle and mark 12 equidistant points on its circumference, labeling them 1 through 12. Ask someone to pick any two numbers, and you can always find a third number on the circle that adds up to 13 with the first two.
