Place Value in mathematics refers to the value of a digit due to its position or location of a digit within a number, i.e., the place of any digit with respect to decimal. Every digit within a number holds a specific place. When we represent the number in standard notation, the placement of each digit is expanded. This arrangement starts from the rightmost position, known as the unit’s place or one’s position. The sequence of place values, moving from right to left, holds units, tens, hundreds, thousands, ten thousand, hundred thousand, and so forth.

In this article, we will discuss the concept of Place Value in Maths in detail including its definition, properties, formula, and important terminology of Place Value. Other than that, we will also discuss types of Place Value Chart, some solved problems, and provide practice questions for a better understanding of the concept of this article.

Place Value in Maths

Meaning of Place Value

The position of a digit determines the Place Value in a number. Each digit holds a specific value based on its position within the number. It’s important to note that the same digits can have varying place values in a number. The determination of Place Value begins from the right side, known as the one’s position.

Progressing from right to left, the sequence of place values includes ones, tens, hundreds, thousands, tens thousands, and so forth. These values are distinct for each position, ensuring that no two digits within the number share the same value.

Place Value Definition

Place Value is defined as the value of a digit based on its position within a number, denoted by ones, tens, hundreds, and beyond. Every digit in a number possesses a distinct and specific place value. Place Value begins at the rightmost digit, representing units, and then progresses to tens, hundreds, thousands, and so forth, each being a successive power of 10.

For example, consider the digit 5 in the numbers 3258 and 5881. In 3258, the Place Value of 5 is 5 tens or 50. Similarly, in 5881, the Place Value of 5 is expressed as 5 thousand i.e., 5,000. It is important to understand that a digit may be the same, but its value varies according to its position within the number.

How to Find the Place Value?

The Place Value of a digit is determined by its position within a number, ensuring that each digit holds a unique value within the number. To know how place value is determined, we observe that the power of 10, representing the place value, increases by one as we move from right to left in the number.

For example, in the number 326, the unit’s Place Value for digit 6 will be 6 × 100 = 6. Similarly, the tens Place Value for digit 2 will be 2×101=20. In the hundreds place, the Place Value for digit 3 will be 3 × 102 = 300.

Properties of Place Value

There are some key properties of place value given below:

  • The Place Value of any single-digit number is same to its face value.
  • In a two-digit number, the Place Value of the tens digit is ten times the digit itself.
  • Place Value is a fundamental principle that a digit’s Place Value is obtained by multiplying the digit by the place value of ‘1’ for the position it occupies.

Place Value Chart

Place Value Charts for numbers help us to ensure proper alignment of digits according to their respective places. These charts provide a clear representation of where each digit should be positioned within a number. To identify the positional values of different digits in a number accurately, we write the individual digits in a number and then utilize a number place value chart to visually inspect their positions. In order to make the process, especially with larger numbers, we divide them into distinct periods separated by commas. Generally, there are two types of place value charts that are widely utilized for this purpose:

  • Indian Place Value Chart
  • International Place Value Chart

Indian Place Value Chart

The Indian Place Value system operates on a pattern known as 3:2:2. In this system, when dealing with larger numbers, we introduce a comma (,) after the first three digits from the right. Subsequently, commas are placed after every two digits. For example, if we consider the number 2369558, it would be written as 2,36,95,558, following this pattern. Place Value of 3 in the number 2,36,95,558 as 3 ten lakhs or 30,00,000. Then, we refer to a provided table to correctly denote the place values corresponding to each position.

International Place Value Chart

This globally accepted Place Value system follows a consistent approach. When dealing with numbers exceeding three digits, a comma (,) is inserted after every set of three consecutive digits, starting from the right. For example, in the case of the number 2369558, we would represent it as 2,369,558. To determine the respective place values, we refer to the provided chart for guidance. The Place Value of 3 in the number 23,695,558 is 3 millions or 3,000,000.

Place Value Chart with Decimals

The Decimal Place Value Chart represents the significance of digits in a decimal number, a system that combines whole numbers and fractions through a decimal point. This point divides the whole number portion from the fractional part. While the whole numbers follow the conventional place value chart of ones, tens, hundreds, and so forth, there is a difference in place value for digits to the right of the decimal point. 

As we move to the right after the decimal point, the place values initiate from tenths, then proceed to hundredths, thousandths, and so forth. Following a Place Value Chart for Decimal numbers provides a clear understanding of these values.

Place Value and Face Value

A number is constructed by arranging digits in specific groupings.

  • Every digit is assigned a distinct position, known as its “Place.”
  • Each digit has a value depending on its place called the Place Value of the digit.
  • The “Face Value” of a digit for any place in the given number is the value of the digit itself.
  • The Place Value of a digit can be calculated by multiplying its face value by the numerical value of its place.

Difference Between Place Value and Face Value

The key differences between Place Value and Face Value in math is listed below:

Place Value

Face Value

The position a digit holds within a number determines its Place Value. The Face Value represents a digit’s actual numerical value within a number.
The Place Value depends upon the digit’s location within the number. It remains constant regardless of the digit’s placement in the number.
In the units place, a digit’s Place Value is a single digit, and as we move left, each subsequent digit’s place value increases by a factor of 10. The Face Value of any digit is always a single digit.

Solved Examples on Place Value

Example 1: Determine the Place Value of the digit 5 in the number 84,520.

Solution:

In the number 84,520, the digit 5 holds a Place Value of 500, specifically, five hundred.

Example 2: Express the given numbers in both numerical and expanded forms:

  • Ten thousand two hundred and thirty-six
  • Seven thousand four hundred and eighty-five

Solution:

For “Ten thousand two hundred and thirty-six”:

In numerical form: 10,236

For “Seven thousand four hundred and eighty-five”:

In numerical form: 7,485

In expanded form: 7,000 + 400 + 80 + 5

Example 3: Given a number with 8 thousands, 7 hundreds, and 8 tens, determine the number.

Solution:

We calculate the Place Value for the respective digits as follows:

8 thousands = 8,000

7 hundreds = 700

8 tens = 80

Adding all Place Value, we obtain: 8,000 + 700 + 80 = 8,780. Hence, the number is 8,780.
