classified of $${\mathtt{\,-\,}}{\mathtt{root4}} = {\mathtt{\,-\,}}{\sqrt{{\mathtt{4}}}}$$ is whole, integar, rational, irrational or real #?
First, you solve it. The answer is - 2. -2 is classified as integer, rational, and real. By the way, a number can be either real or irrational, but not both. If something is natural, whole, an integer, and/or rational then it is also real.
Definitions:
Natural: Counting numbers (1, 2, 3, 4, 5 ...)
Whole numbers: Natural number, but also including 0
Integers: Whole Numbers and their opposites (the positives and negatives)
Rational Numbers: Decimals or fractions that terminate (don't go on forever) or decimals that repeat in a pattern
Real: Any number that is natural, whole, an integer, and/ or rational
Irrational: Any term that has a decimal or fraction that does not terminate and continues in a seemingly random way (ex. Pi [3.14159...])
