Number properties form the foundation of arithmetic and algebra. Commutative, associative, distributive, identity, and inverse properties govern how numbers interact and enable simplification and problem-solving strategies.
What Students Will Learn
- Identify and apply the commutative property
- Identify and apply the associative property
- Apply the distributive property
- Understand identity and inverse properties
- Use properties to simplify expressions
Frequently Asked Questions
What is the commutative property?
Order does not matter for addition or multiplication: a + b = b + a and a × b = b × a.
What is the distributive property?
Multiplication distributes over addition: a(b + c) = ab + ac. This is key for expanding and factoring.
What are identity elements?
The additive identity is 0 (a + 0 = a). The multiplicative identity is 1 (a × 1 = a).
