Indian Numeral System

Indian Number System The Indian place value chart is a writing system used to represent numerals in India. Prior to the development of numbers, people typically used objects such as stones, pebbles, sticks, and rocks to count things. When numbers were first written, it was vital to create a uniform counting method in order to simplify the difficult nature of writing lengthy numbers. Eventually, the Indian System was developed and people began counting using symbols or digits. The chart for ones, tens hundreds of thousands of lakhs, and billions was been simplified using the chart for the Indian numeral system.

In the Indian system of numeration, the values of numbers are represented by a set of symbols. Based on the classifications that are applied to the various place values in numbers. Therefore, individuals must understand the distinction between number systems and other number systems.

Usage of Commas

Separators (commas) are needed after every period when representing a number in its conventional numeral form according to the Indian number system. Using separators after each period, the number 384756182 can be better expressed in the traditional Indian numeral system as 38,47,56,182. It should be noted that the periods in the Indian numeral system are divided according to the rule 3:2:2. This indicates that beginning from the right, the first comma should be placed after three digits, and further commas should be placed after every two digits. For instance, observe the commas in the number 6,95,42,189.

Number Names in the Indian Number System

The number names in the Indian number system are determined by the nomenclature for the various place values of the number’s digits. When writing the number names of the Indian numerals, the following factors must be considered:

  • According to the Indian number system, commas are used to differentiate between periods. Therefore, these periods can be utilized to read the different place values in a number while writing the number names.
  • In the Indian number system, the periods are separated according to the rule of 3:2:2, and the number name can therefore be written without difficulty.
  • The Indian number system expresses its periods as ones, thousands, lakhs, and crores.

Therefore, we begin putting the name of the period after each number in the period and we exclude the period that contains all zeros.
