What is Place Value of Numbers in Math? (Place Value Chart, Definition & Examples) – BYJUS

# Place Value

The value of each digit in a multi-digit number is known as the place value. The place value is determined by the position of the digits in the number. For example, each 5 in the number 555 has a different value. The value of each 5 increases from left to right.

Place value helps us find the value of the digit in a number. When we say that the bill for groceries was $89, we say eighty-eight dollars, and we are in fact applying place value. If the bill was$99 we say that this number is ninety-nine dollars. The eighty shows the value of the 8 at the tens place ($89) and the nine shows the value of the 9 at the ones place ($89). Let us go through a few more examples to understand the place value of numbers.

For example, 469 can be represented as: Where,

4 represents 4 hundreds or 400,

6 represents 6 tens, or 60,

9 represents 9 ones.

Now, if we interchange the position of the numbers and write 694, then: If you observe, the digit 6 is in the hundreds place, so it represents 6 hundreds or 600. 9 is at the tens place, which represents 9 tens or 90.

So, the place value of 9 is 90.

4 is at the ones place, which represents 4 ones and its place value is 4.

This shows us that using the same digits, we can form different numbers. We can also compare two numbers using their place values.

## The Place Value Chart

To understand place value easily and effectively, we make use of the place value chart. The place value chart has the ones place in the rightmost column. It is followed by the tens place to the left and then hundreds, thousands, ten thousands, and so on.

The place value chart also helps us to group place values. Grouping place values is very useful when we study large numbers. For example, 568293 can be written using place value as follows: The number 568293 is separated into two periods, the thousands period and the ones period.

## Solved Place Value of Numbers Examples

Example 1:

Make a place value chart and answer the questions for the number 576623.

What is the standard form of the number?

What is the place value of the digit 5?

What is the value of the digit 6 in both places?

Compare the digit 6 in the thousands period and the digit 6 in the ones period.

Solution:

The place value chart is: The number, in the standard form, is 576,623.

The value of the digit 5 is 5 hundred thousand or 500000.

The value of the digit 6 in the thousands place is 6000.

The value of the digit 6 in the hundreds place is 600.

The value of the digit 6 in the thousand place is 10 times the value of the digit 6 in the hundreds place:

6000 = 10$$\times$$ 600
