How to Write Numbers up to 10-Digits?
The 10-Digits number can be written in two ways, one is the International number system and another one is the Indian number system.
In the International number system, the 10-digit number is expressed by using commas just after every three digits from the right. The smallest 10-digit number is written as 1,000,000,000 and is called a billion or one billion and it is written as 1 followed by 9 zeros. Since the third comma after the 9th digit from the right denotes the start of a billion, so this number would be called 1 billion in the International number system.
In the Indian number system, the first comma comes after three digits from the right after the hundred's place value and the next comma comes after every two digits, and so on. So the smallest 10 digit number would be written as 1,00,00,00,000 in the Indian system. Since the third comma after the 7th digit from the right denotes the start of a crore, so this number would be called 100 crores or one Arab in the Indian number system.

- Digit 6 PV = 6 × 100000 = 600000
- Digit 7 PV = 8 × 1000000 = 8000000
- Digit 8 PV = 4 × 10000000 = 40000000
- Digit 9 PV = 4 × 100000000 = 400000000
- Digit 10 PV = 5 × 1000000000 = 5000000000
- Observe the different ways of placing commas in the number 5000000000: International Place Value System: 5,000,000,000; Indian Place Value System: 5,00,00,00,000
