Whole Numbers: numbers 0, 1, 2, 3, 4......
Integers: numbers ....-3, -2, -1, 0, 1, 2, 3....
-Positive Integers: integers that are greater than 0 (1, 2, 3...)
-Negative Integers: integers that are less than 0 (-1, -2, -3...)
-The integer 0 is neither negative or positive
Rational Numbers: a number a/b where a and b are integers and b is not equal to 0. For example: (-1/2) is a rational number because it can be written as (1/-2), as well. When you divide rational numbers your decimal expansion will repeat or end (0.5, 0, .1313...)
Irrational Numbers: numbers whose decimal expansions never repeat. Examples: 1.414213562373...(sqrt(2)) or 3.141592653589...(pi)
Real Numbers include:
-all whole numbers
-rational numbers
-irrational numbers
Real Numbers DO NOT include:
-imaginary numbers such as sqrt(-1)
-infinity
