Imagine you have a bag full of numbers, and no matter which ones you pick, they always add up to something special. That’s what it feels like when numbers act like magic! For example, if you take any number, double it, add 6, divide by 2, and subtract your original number, poof! You end up with 3 every time. It’s like a secret spell that works no matter which number you choose.
Examples
- You pick 13, reverse it to get 31, then subtract: 31 - 13 = 18
- You choose 72, reverse it to get 27, and do the same math: 72 - 27 = 45
- Every time you try this trick with a different number, it always gives you a multiple of 9
