Study Notes
Axioms for Real Numbers
- Real numbers are equal to themselves (reflexive property). For any real number a, a = a.
- If a equals b, then b equals a (symmetric property).
- If a equals b and b equals c, then a equals c (transitive property).
Addition Axioms
- Adding any two real numbers results in another real number (closure property).
- The order of addition does not affect the result (commutative property).
- The way numbers are grouped in addition does not affect the result (associative property).
- Zero is the additive identity for real numbers. a + 0 = a for any real number a.
- Every real number has an additive inverse. For any real number a, there exists a unique real number –a such that a + (–a) = 0.
Multiplication Axioms
- Multiplying any two real numbers results in another real number (closure property).
- The order of multiplication does not affect the result (commutative property).
- The way numbers are grouped in multiplication does not affect the result (associative property).
- One is the multiplicative identity for real numbers. a × 1 = a for any real number a.
- Every non-zero real number has a multiplicative inverse (reciprocal). For any non-zero real number a, there exists a unique real number 1/a such that a × (1/a) = 1.
- Multiplication distributes over addition. a × (b + c) = (a × b) + (a × c) for any real numbers a, b, and c.
Important Note
These axioms are fundamental to understanding how real numbers interact with arithmetic operations. They underpin the rules and properties used in algebra. These axioms reflect the common-sense understanding of numbers and provide a rigorous framework for more complex mathematical concepts.
