Math
Real number properties.
Definition
The fundamental properties that govern arithmetic operations with real numbers, including commutative, associative, distributive, identity, and inverse properties.
Examples
Real-world.
- 1 Commutative: 3 + 5 = 5 + 3 and 2 × 7 = 7 × 2
- 2 Associative: (2 + 3) + 4 = 2 + (3 + 4)
- 3 Distributive: 3(x + 4) = 3x + 12
Key Fact
Commutative: a+b = b+a; Associative: (a+b)+c = a+(b+c); Distributive: a(b+c) = ab+ac
