How to Do the 1089 Number Trick | Magic Tricks?

Pick a number between 1 and 9, it’s your secret number, and do some simple steps to get to a surprising result.

Let's say you pick 7, like the number of days in a week. Now, write that number down three times in a row: 777. This is your starting point.

Now, take that number and divide it by 7. So, 777 ÷ 7 = 111.

Then, take the result and multiply it by 9, like counting 9 steps forward. 111 × 9 = 999.

Finally, divide that number by 9, just like sharing candies with friends: 999 ÷ 9 = 111.

No matter which number you picked at the beginning (like your favorite toy or snack), this trick always ends up with 111, it's like a little number puzzle that gives you the same answer every time!

This works because of how numbers behave when they're grouped and shared. It’s like having 3 cookies, sharing them equally between 7 friends, then multiplying by 9 more cookies, and finally dividing again, to always end up with the same snack count!

Examples

  1. A child picks a number, reverses it, subtracts, and gets 1089 every time.
  2. Using the number 45, reversing gives 54. Subtracting 45 from 54 equals 9, then multiplying by 9 gives 81.
  3. Try this trick with any three-digit number, like 321, and see it turn into 1089.
