How to Write Numbers up to 10Digits?
The 10Digits 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 10digit number is expressed by using commas just after every three digits from the right. The smallest 10digit 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 9^{th} 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.

How to Decompose 10Digit Numbers?

 Digit 10 – One Arab (Hundred Crores) / Billion
So let us take a random 10digit number  5448626840, and see how it gets decomposed.
Here, PV stands for Place Value:
 Digit 1 PV = 0 × 1 = 0
 Digit 2 PV = 4 × 10 = 40
 Digit 3 PV = 8 × 100 = 800
 Digit 4 PV = 6 × 1000 = 6000
 Digit 5 PV = 2 × 10000 = 20000
 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
Important Notes:
 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
 Observe the different names according to the Indian Number System and the International Number System:
 One Lakh is equal to One Hundred Thousand
 Ten Lakh is equal to One Million
 One Crore is equal to Ten Million
 Ten Crore is equal to Hundred Million
 One Arab (Hundred crores) is equal to One Billion
