Smallest number more than fifteen thousand

To find the smallest number more than fifteen thousand, we need to understand the concept of place value and number sequencing. Let's break down the process into steps:

Step 1: Understanding place value
- Place value refers to the value of a digit based on its position within a number.
- In the decimal system, the place values are as follows: units, tens, hundreds, thousands, ten thousands, hundred thousands, and so on.

Step 2: Understanding fifteen thousand
- Fifteen thousand is a number composed of two parts: the thousands place and the units place.
- In fifteen thousand, the digit "1" represents the thousands place, and the digit "5" represents the units place.

Step 3: Incrementing the number
- To find the smallest number more than fifteen thousand, we need to increment the value in the thousands place while keeping the units place unchanged.
- Since the smallest digit in the thousands place is "1" and we need a number greater than fifteen thousand, we increment the thousands place to the next available digit, which is "2."

Step 4: The smallest number more than fifteen thousand
- By incrementing the thousands place from "1" to "2" and keeping the units place unchanged as "5," we get the smallest number more than fifteen thousand.
- The smallest number more than fifteen thousand is twenty thousand five.

Therefore, the smallest number more than fifteen thousand is twenty thousand five.
