## Indian Numbering System

The most widely and globally used system of numbers is Hindu-Arabic number system. In the classical period of Indian mathematics (400 AD to 1200 AD), important contributions were made by scholars like Aryabhata, Brahmagupta, Bhaskara II, and Varāhamihira.

**The decimal number system**in use today was first recorded in Indian mathematics.- Indian mathematicians made early contributions to the study of the concept of
**zero as a number, negative numbers, arithmetic, and algebra** - In addition,
**trigonometry**was further advanced in India, and, in particular, the modern definitions of sine and cosine were developed there. - These mathematical concepts were transmitted to the Middle East, China, and Europe and led to further developments that now form the foundations of many areas of mathematics.

Hindu number system was invented by Indian mathematicians between the 1^{st} and 4^{th} centuries. Later, by the 9^{th} century, this system was adopted by Arabic mathematicians and finally, this came to be known as Hindu-Arabic number system. It future spread to Europe.

Hindu-Arabic numbers have 10 digits or symbols: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. It is a place-value system where the digit zero has its own importance.

**Representing a number**

To write a number, the digits are placed from left to right under the places labelled as Units, Tens, Hundreds, Thousands… etc., and read accordingly. For example, consider number 393071425. This number is represented as shown below and read asThirty-nine* crores thirty lakh seventy-one thousand four hundred and twenty five.*

Ten Crores | Crores | Ten Lakhs | Lakhs | Ten Thousand | Thousands | Hundreds | Tens | Unit |

3 | 9 | 3 | 0 | 7 | 1 | 4 | 2 | 5 |

## Difference between Indian and International Numbering System

**Different Names**:- In the Indian numeral system, the place values of digits go in the sequence of Ones, Tens, Hundreds, Thousands, Ten Thousand,
**Lakhs, Ten Lakhs, Crores and so on. The Indian Numbering system uses lakh or lac (100,000 or 1,00,000 in the Indian system), crore (10,000,000 or 1,00,00,000) in the Indian system to express large numbers.** - In International Numeral System the place values of digits go in the sequence of Ones, Tens, Hundreds, Thousands, Ten Thousand,
**Hundred Thousands, Millions, Ten Million**and so on, in the international numeral system. - How many lakhs make a million?

How many millions make a crore?

- In the Indian numeral system, the place values of digits go in the sequence of Ones, Tens, Hundreds, Thousands, Ten Thousand,
**Placement of Comma or Separator:**Commas are placed in large numbers to help us read and write them easily.**In Indian and international systems, the commas are placed at different positions.**- The Indian numbering system uses comma or separators differently from the international norm.
- Instead of grouping digits by threes as in the international system, the grouping is done in a repeating pattern of 3,2,2 (from least significant digits).
- As per the Indian numeral system, the first comma is placed after the hundreds place post which they are placed after every two digits. E.g., 1,23,45,67,890
- As per international numeral system, the first comma is placed after the hundreds place, then they are placed after every three digits. E.g., 1,234,567,890

Example:

Indian system | International/Western system |

5,00,000
Five lakhs |
500,000
Five Hundred Thousands |

12,12,12,123
Twelve crores twelve lakh twelve thousand one hundred and twenty three |
