Magic numbers are special because they show up in cool ways. Like the number 7, you have 7 days in a week, 7 colors in the rainbow, and even 7 deadly sins! If you take any number and add up its digits until you get one digit, it's called a magic trick. Try with your age or your favorite number, it always works!
Examples
- Your favorite number is 12, add up its digits (1 + 2), and you get 3!
- If you multiply 9 by any number, like 7 × 9 = 63, then 6 + 3 = 9.
- You have 7 friends, but the phone rings 7 times, magic!
