Fundamentals of Integers
Integers are basically Whole numbers with + and – sign. It means that the numbers -1, -2, -3, -4 …….. 0 ……….1, 2, 3, 4, 5, 6……. all are integers.
-
The 0 (zero) is neither positive nor negative integer.
-
The integer does not have decimal or fraction.
e.g. 3.4, 5.8, 25.6, 89.34, 2/5, 8/9, 15/25, are not integers.
-
A positive integer is always greater than “0”.
Suppose ‘x’ is a positive integer, it means that values of ‘x’ should be 1, 2, 3, 4, 5…….25, 26, 28 ……..545,546, 548……………. .
-
A negative integer is always less than “0”.
If condition is given that ‘x’ is a negative integer than take the value for ‘x’ as -1,-2,-3,-4,-5………….
