\r\n Any number that is not a fractional number or a decimal is an integer. To better understand integers, we have to look into\r\n its relation to other integers.\r\n
\r\n\r\n Natural numbers are numbers that we use for counting, ordering and comparing objects — such as 1, 2, 3, 4, and so on.\r\n Natural numbers were the first numbers to be discovered.\r\n So, you can say that any number that is not zero or a fractional number or a negative number is a natural number.\r\n The set of natural numbers is often denoted by letter \\(\\mathbb{N}\\).\r\n
\r\n\n If we include 0 in the set of natural numbers then it becomes whole numbers. Thus, whole numbers are 0, 1, 2, 3, 4, and so on.\r\n In other words, any number that is not a fractional number or a negative number is a whole number.\r\n The set of whole numbers is denoted by letter \\(\\mathbb{W}\\).\r\n
\r\n\n Now, if we take the set of whole numbers, and include negative natural numbers to it then it becomes set of integers.\r\n The set of integers is denoted by letter \\(\\mathbb{Z}\\).\r\n
