Definition – The sum of a set of numbers is the same no matter how the numbers are grouped. Example – 2+(3+4)=(2+3)+4 Example – 2+(3+4)=(2+3)+4 Example – (10+12)+14=10+(12+14) Example – (10+12)+14=10+(12+14)

5. Associative Property of Multiplication Definition – The product of a set of numbers is the same no matter how the numbers aregrouped. Definition – The product of a set of numbers is the same no matter how the numbers aregrouped. Example – 5x(3x2)=(5x3)x2 Example – 5x(3x2)=(5x3)x2 Example – 12x(16x10) = (12x16)x10 Example – 12x(16x10) = (12x16)x10

6. Distributive Property Definition – The sum of two addends multiplied by a number is the sum of the product of each addend and the number. Definition – The sum of two addends multiplied by a number is the sum of the product of each addend and the number. Example – 5(20 + 1)= 5x20+ 5x1 Example – 5(20 + 1)= 5x20+ 5x1 Example – 6(7 + 15)= 6x7+ 6x15 Example – 6(7 + 15)= 6x7+ 6x15
