**Numbers can be written in a general form.**

Two-digit number ab will be written as ab = 10a + b.

The sum of a 2-digit number & the number acquired by interchanging its digits is always divisible by 11. The difference between the 2-digit number & the number acquired by interchanging its digits is always divisible by 9.

The general form of a 3-digit number is 100a + 10b + c. The difference between the 3-digit number & a number acquired by reversing its digits is always divided by 99.

**General form of numbers**

The general form of numbers is useful in solving number games or puzzles.

Here is the general representation of a number:

For a two-digit number, assume AB = A × 10 + B × 1

For instance: 95 = 90 + 5 = 9 × 10 + 5 × 1

For a three-digit number

Assume ABC

= A × 100 + B × 10 + C × 1

= 100 A + 10 B + C

For instance: 123 = 100 + 20 + 3

= 1 × 100 + 2 × 10 + 3 × 1
