How Does Each Digit Hold a Value in Any Given Number?

Your mom is still a mom whether she is in the kitchen, garden, living room, or the basement. But digits like 5 at different places (for example, tens or hundreds of places) means something different. Every digit in a number has a place value in Mathematics. Place value is the value represented by a digit in a number based on its place in the number. In this article we'll help you out to understand it in an easy way.


Place value for Grade 4 is important because it serves as a foundation for grouping, multiple-digit multiplication, and other operations in the decimal system, as well as a starting point for learning about other base systems. By understanding this you'll be able to understand the key differences like Rs. 50 you got for your birthday and the Rs. 500 price tag on the Remote Car for which you're saving for.


In Mathematics, the position or place of a digit in a number is referred to as place value. Each digit has a specific place in a number. The position of each digit will be expanded when we represent the number in general form. Those positions begin with a unit position, often known as one's position. Units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on are the place values of a number's digits in sequence from right to left.


What Is Place Value?

The value of each digit in a number is determined by its position in that number. We have given a chart below, that is a place value chart which helps in the identification of large numbers. This place value chart is read from left to right. In the Indian system, we begin arranging numbers from right to left in groups of three, and then in groups of two. The place value chart is divided into intervals, which include ones, thousands, lakhs, and crores.


The 5 in 250, for example, indicates 5 tens, or 50; whereas, the 5 in 5,126 denotes 5 thousands, or 5,000. It is important to understand that while a digit can be the same, its value is determined by its position in the number. A place value grid, such as the one shown below, will most likely be used to understand place value in a better way.

International Place Value Chart

The International place value chart is a place value system that is used in many countries around the world. We use a place value chart to understand the place value of each digit so that we can identify each digit. We start grouping the numbers from right to left in groups of three, called periods, and we place a comma or space after each period to make the number easier to read.

Place, Place Value and Face Value

A number is made by grouping a few digits together.

  • Each digit will have a fixed position called its place.

  • Each digit’s value depends on its place, which is known as the place value of the digit.

  • The face value of a digit in the given number is just the value of the digit itself.

  • The place value formula of a digit can be written as the product of face value of the digit and value of the place.

That is,

Place value = (Face value of the digit) × (Value of the place)


Example:

In the number 874321, write the digit which is in:

(a) hundreds place

(b) hundred thousand place

(c) ten thousand’s place

(d) and One’s place

Sol:

(a) A number in hundreds places is 3.

(b) A number in a hundred thousand places is 8.

(c) A number in ten thousand’s place is 7.

(d) The number in One’s place is 1.

Conclusion

Having a strong understanding of place value is a good step because it gives you the key number knowledge you need to solve calculations like addition, subtraction, multiplication, division, and fractions. It would be difficult to write numbers, identify one more or one less, count forwards and backwards, or compare numbers if you are not thorough about place value. Moreover, understanding place value in Maths has a significant impact on how we think about basic concepts such as money. Understanding place value can help you figure out how much something costs when we wish to buy it.

FAQs on Understanding Place Value in the Number System

1. What is the difference between the face value and the place value of a digit?

The magnitude of a digit's face value is its natural magnitude. It doesn't matter where the digit is in the number. A digit's place value is determined by its position in the number. The 5 in the number 353, for example, has a face value of 5 and a place value of 50.

2. How will place value help me multiply numbers?

Having a thorough understanding of place value will help young learners in multiplying fractions and decimals. Children will also use their knowledge of place value in digits to multi-digit numbers when using formal written methods of multiplication.

3. Why is place value for Grade 4 important?

When teaching Maths to any kid, the most important concept is place value. It is the foundation of all mathematical concepts from preschool to algebra, and it is required for a thorough understanding of the subject. Students will not be able to progress until they have understood Place Value as a basic concept first.
