2 PropertiesA property is something that is true for all situations.
3 Commutative Property of Addition In a sum, you can add the numbers in any order.A + B = B + AOrder doesn’t matter
4 Commutative Property of Multiplication In a product, you can multiply the numbers in any order.A x B = B x AOrder doesn’t matter
5 Associative Property of Addition Changing the grouping of the numbers in a sum does not change the sum.Associative Property (a + b) + c = a + (b + c)Example: (6 + 4) + 3 = 6 + (4 + 3)Who’s hangin’ with who?
6 Associative Property of Multiplication Changing the grouping of the numbers in a product does not change the product.Associative Property (a · b) · c = a · (b · c)Example: (6 · 4) · 3 = 6 · (4 · 3)Who’s hangin’ with who?
7 Identity Property of Addition The sum of a number and zero (additive identity), is the number.If you add 0 to any number, the number stays the same.
8 Identity Property of Multiplications The Product of a number and one (multiplicative identity), is the number.If you multiply any number times 1, the number stays the same.
