Study Notes
Number Types in Algebra II
- Natural Numbers: Consist of all positive counting numbers starting from 1 (e.g., 1, 2, 3, ...).
- Whole Numbers: Extend natural numbers by including zero (e.g., 0, 1, 2, 3, ...).
- Integers: Comprise whole numbers along with their negative counterparts (e.g., ..., -3, -2, -1, 0, 1, 2, 3, ...).
Rational and Irrational Numbers
- Rational Numbers: Any number expressible as a fraction p/q where p and q are integers, and q is not zero; includes repeating and terminating decimals (e.g., 1/2, 0.75).
- Irrational Numbers: Numbers that cannot be written as a simple fraction; represented by nonterminating, nonrepeating decimals (e.g., √2, π).
Additional Key Concepts
- Absolute Value: Represents the distance of a number from zero on the number line, always non-negative (e.g., |−3| = 3).
- Extraneous Solution: A solution derived from an equation that does not satisfy the original equation; must be checked for validity.
