In math, number systems are the means by which numbers are expressed mathematically with the help of a specific set of digits. There are basically four types of number systems.
A binary number contains only two digits, 0 and 1. They are mostly used in computer languages.
There are ten digits from 0-9 in this number.
The number ranges from 0 to 7.
There are digits ranging from 0 to 9 and alphabets ranging from 'A' to 'F' that make up the number. Here,
The number N contains all positive numbers from 1 to all possible positive numbers. This can also be written as N= [1, 2, 3... ].
The sets of numbers in this set are generally denoted by the letter W. They include 0 to all possible positive numbers. This can be written as W= {0,1,2,3….}
This consists of every number from negative infinity to positive infinity, which can be represented by both the letters I and Z.
