# . What is the Meaning of Large Numbers in mathematics

Everyone learns how to count numbers at a very young age from one digit to seven digits. This is done with the help of a place value system. There are two place value method to follow - the Indian Place Value System and the International Place Value System.

When writing big numbers, we always keep in mind the place value system to make sure it is written correctly. According to India's place value system, where the number is written, each set of digit divided by a comma is called a period. These periods are called one, thousands, lakhs and so on. One period contains first three digits of the large number, from the right. Thousands of period consists of the next two digits. The period of lakhs consists of the next two digits and continues.

According to the international place value system, numbers are divided into periods. These times are called one, thousands, millions, billions and so on. In this system, each period has three numbers.

Let's look at an example: 12,457, 891. According to the International Place Value system, this reads as twelve million, four hundred and fifty-seven, eight hundred and ninety-one.

Some large numbers are read and labelled as follows:

1,000,000,000 = one billion

1,000,000,000,000 = one billion

The following table shows how to read and write numbers according to the International place value system.
