Try this out.

Take 2 numbers and form the biggest number possible from the two digits and subtract the smallest number possible.

The Answer is (the two 2 digits of the asnwer equals to 9)

Before I reveal the number trick,

Here are a few examples....

__Example 1__

2 Numbers = 9 & 2

Biggest number possible - Smallest number possible

92 - 29 = 63 (6+3 = 9)

2 number = 9 & 2

9 - 2 = 7

The answer is a multiple of 9 and the answer is the difference between the 2 numbers choosen, multiply by 9.

Hence, 7 x 9 = 63.

__Example 2__

4 & 5

54 - 45 = 9

__Example 3__

1 & 5

21 - 15 = 36 (3+6 =9)

Amazing? Well, let's find out the Number Trick

Why is works? x y

10 x + y 10 y + x

(10 x + y) (10 y + x)

9 x - 9 y

9 (x - y)
