Place Value-International and Indian System
Indian Place Value System
Place value is defined as the numerical value of each digit in a number depending on its position or place.
Let’s take a number 155. Here we note that the digit 5 is used twice in this number. Both 5 have a different values.
So the place value of right most 5 is ones and the one in the center is tens.
In Indian place value system, The place value chart separated in groups known as periods i.e. ones, thousands, lakhs, crores and Arab and so on.
Above number is read as Fifty two arab, ninety three crore, sixty two lakh, forty five thousand, eight hundred seventeen.
The 1st period consists of (Ones, Tens, Hundred).
The 2nd period consists of (Thousand and 10 Thousand, and 1 Hundred).
The 3rd period consists of (1 Lakh and 10 Lakh).
The 4th period consists of (Crore and 10 Crore).
The 5th period consists of (Arab and 10 Arab).
We read place value chart from left to right. we start grouping the number from right in group of 3 and further group of 2.
In the number 50,34,21,987 the place value of each digit are:
7 – Ones Place
8 – Tens Place
9 – Hundreds Place
1 – Thousands Place
2 – Ten Thousands Place
4 – Lakhs Place
3 – Ten Lakhs Place
0 – Crores Place
5 – Ten Crores Place
A Place value chart shows the value of each digit in a numeral based on its position and recognize large numbers.
Lakhs | Ten thousands | Thousands | Hundreds | Tens | ones |
2 | 3 | 4 | 5 | 6 | 7 |
234,567 Two hundred, thirty four thousand, five hundred sixty seven.
L | TTh | Th | H | T | O |
5 | 5 | 5 | 8 | 7 | 2 |
555,872 Five hundred, fifty five thousand, eight hundred seventy two.
International Place Value System
The place value chart used in many countries of the world is called the International Place Value Chart.
In International place value system, we start grouping the number from right in group of 3, called periods namely Ones, Thousands and Millions(nine places from right to left).
Every periods is made up of three place values. Ones period has three values are ones, tens and hundreds.
The next period is made up of one, ten and hundred thousands.
The 1st period consists of (Ones, Tens, Hundred).
The 2nd period consists of (Thousand, 10 Thousand, and 100 Thousands).
The 3rd period consists of (Million, 10 Million and 100 Million).
The 4th period consists of (Billion, 10 Billion and 100 Billion).
The next three places make millions period and the pattern continues. To read easily the number, we put the comma or space after every three digits from the right.
In the number 50,34,21,987 the place value of each digit are:
7 – Ones Place
8 – Tens Place
9 – Hundreds Place
1 – Thousands Place
2 – Ten Thousands Place
4 – Hundred Thousands Place
3 – Millions Place
0 – Ten Millions Place
5 – Hundreds Millions Place
When we read very large numbers, we arrange the numbers into periods with the help of comma as a separator.
Let’s see some examples,
95823036. Now check the position of each digit.
95,823,036
Ninety five million, eight hundred twenty three thousand, thirty six.
TM | M | HTh | TTh | Th | H | T | O |
9 | 5 | 8 | 2 | 3 | 0 | 3 | 6 |
34,091,258
Thirty four million ninety one thousand two hundred fifty eight.
5,763,241

Seven hundred thirty five million four hundred twenty one thousand three hundred eighty six.
7,253,831
Seven million two hundred fifty three thousand eight hundred thirty one.
30,000,005
