## How to generate random single (odd) or double numbers easily?

Single (odd) numbers are the numbers that can not be divided by double numbers without remained any integer. 1, 3, 5, 7, 9, 11….29……67…..191 are the few examples of single numbers.

**You can detect a single number with its last digit**; if it is single like 1, 3, 5, 7 or 9, that number is a **single (odd) number**.

Similar to this logic, if a number’s last digit is a double number like 0, 2, 4, 6 or 8, we can call that number as a **double number**.

You might interest why “0” is being accepting as a double number. Well, the answer is easy; double numbers are the numbers that have remained “0” after they have been divided by a double number. For example, 12 / 6 = 2. Remained number is 0 (nothing). Zero “0” is a number that will have nothing (0) remained whatever it has been divided. 0 / 5 = 0 (Remained number is 0). 0 / 5179 = 0 (Remained number is 0). That’s why the zero “0” is a double number.

With this simple trick of math, you can easily generate single or double numbers from your mind.
