1. Properties of Numbers Flipbook

2. Addition and Multiplication Properties of Numbers Property of Zero Commutative Property Associative Property Identity Property Distributive Property

3. Property of Zero

4. Commutative Property Addition Multiplication *Think of a commute to work – from home to work and work to home - order switched, same distance (same answer)

5. Associative Property Addition Multiplication *Think of associate – at a party it doesn’t matter which group of friends you talk to first. In the end you will talk to everyone. - Talk to everyone (same final answer)

6. Identity Property Addition Multiplication *Think of your identity – No matter what you change about yourself, you are still you. • Adding 0 to 5 won’t change 5’s identity. • Multiplying 1 to 7 won’t change 7’s identity.

7. Distributive Property Multiplication distributed over addition. For any numbers a, b, and c, a(b + c) = ab + ac Example: 8(6 + 7) = 8 · 6 + 8 · 7 OR Multiplication distributed over subtraction. For any numbers a, b, and c, a(b – c) = ab – ac Example: 6(5 – 2) = 6 · 5 – 6 · 2
