- The Natural Numbers: N ( Includes numbers starting from 1, 2 , 3, 4… does not include 0 )
- The Whole Numbers: No (o is subscript) (Includes number 0 + natural numbers)
- Integers: Z ( Include all positive, negative numbers and 0)
- Positive Integers: Z
^{+} - Negative Integers: Z
^{– } - Rational Numbers: Q (Has nominator and denominator)
- Real Numbers: R ( Includes irrational numbers like √2 , Π etc.)
- Complex Numbers: C ( These are of form a + bi, a and b can be any integers)
