What is a Number System?

You most likely definitely know what a number system is - ever know about Binary numbers or hexadecimal numbers? Basically, a number framework is an approach to speak to numbers. We are used to using the base-10 number system, which is also called decimal. Other common number systems include base-16 (hexadecimal), base-8 (octal), and base-2 (binary).

The value of every digit in a number can be determined −

• The digit
• The position of the digit in the number
• The base of the number framework (where the base is characterized as the aggregate number of digits accessible in the number framework)

Decimal Number System

The number system that we use in our everyday life is the decimal number system. Decimal number system has base 10 as it utilizes 10 digits from 0 to 9. In decimal number system, the progressive positions to one side of the decimal point speak to units, tens, hundreds, thousands, and so on.

Each position speaks to a particular power of the base (10). For instance, the decimal number 9999 comprises of the digit 4 in the units position, 3 in the tens position, 2 in the hundreds position, and 1 in the thousands position. Its value can be composed as :

= (9 x 1000)+ (29x 100)+ (9 x 10)+ (9 x l)

= (9 x 10³)+ (9 x 10²)+ (9 x 10¹)+ (9 x l0⁰)

= 9000 + 900 + 90 + 9

= 9999
