Now, here’s where the magic happens: the result is always a multiple of 9! Let's explore why this happens.

The Math Behind the Magic:

To understand this trick, let’s represent your number as `10a + b`, where `a` is the tens digit and `b` is the units digit. According to the trick:

• The sum of the digits is `a + b`.
• Subtracting the sum from the original number gives us:
•  `(10a + b) - (a + b) = 9a`

What does this mean? The result is always `9a`, a multiple of 9!

Here is a list of numbers and their associated symbols. Notice how all multiples of 9 have the same symbol:

Number	Symbol
9	♦
18	♦
27	♦
36	♦
45	♦
54	♦
63	♦
72	♦
81	♦

Each time you perform the trick, the result you get will always point to a multiple of 9. And since all multiples of 9 share the same symbol, it creates an illusion of prediction!

This trick plays on a beautiful property of the base-10 number system and simple arithmetic. The predictability of the outcome gives it a mystical aura, making it a wonderful conversation starter or an engaging trick to impress your friends.
