## Introduction

**What is Place Value?**

In the realm of mathematics, the concept of place value plays a crucial role in understanding the numerical value of digits within a number. It forms the foundation for working with numbers and is essential for various mathematical operations. Let’s delve into the world of place value and explore its significance.

## Analogy of Definition

**The Essence of Place Value**

Place value refers to the value of a digit based on its position within a number. Each digit in a number holds a specific place value, which determines its contribution to the overall value of the number. The position of a digit within a number is a key factor in determining its place value.

## Method

**Understanding Place Value **

Place value is the value that a digit holds based on its position in the number. In a number, the value of each digit can be expanded based on its position. For example, if we take the number 58270, the place value of 8 is thousand, and if we change the position of 8 and 2, making the number 53870, then the place value of 8 is hundred. **The place value of a digit is thus based on its position in the number. **

**Place Value Chart **

Place Value Chart simplifies understanding the concept of place value. It helps us know the place value of each digit in the number.

By placing the digits in the place value chart, we can know its place value easily, like in the figure below

For the number 283, 527, we can read the chart as

Place value of 2 = Hundred Thousands or 200,000

Place value of 8 = Ten Thousands or 80, 000

Place Value of 3 = Thousands or 3,000

Place Value of 5 = Hundreds or 500

Place Value of 2 = Tens or 20

Place Value of 7 = Ones or 7

Hence, with the help of the chart, we can know the place value of numbers easily. Furthermore, it also helps us in expanding the number. The expanded form of the number 283, 527 would be 200, 000 + 80, 000 + 3, 000 + 500 + 20 + 7.

**Understanding Decimal Place Value**

When it comes to decimal numbers, the concept of place value extends to the digits that appear after the decimal point. The decimal place value chart is a visual representation that illustrates the value of each digit in a decimal number based on its position. Understanding the decimal place value is essential for working with decimal numbers and performing operations involving decimals. For decimal numbers, the decimal place value of the digit right after the decimal is tenths and the place value becomes 10 times smaller as we move towards right.

To understand the decimal place value, let’s take the number 46. 758,

For the whole number part before the decimal, 4 is in the tens place and its place value is 40 while 6 is in the ones place and its place value is 6.

For the digits after decimal,

7 is in the tenths place and its place value is 0.7

5 is in the hundredths place and its place value is 0. 05

8 is in the thousandths place and its place value is 0.08.

## Examples

**Exploring Place Value in Numbers**

Let’s consider the number 3,215. In this number, the digit 3 holds the place value of thousands, the digit 2 holds the place value of hundreds, the digit 1 holds the place value of tens, and the digit 5 holds the place value of ones. Each digit’s position within the number determines its place value, contributing to the overall value of the number.
