Properties of Algebra

2
Commutative Property of Addition Definition – The sum of a group of numbers is the same regardless of the order in which the numbers are arranged. Definition – The sum of a group of numbers is the same regardless of the order in which the numbers are arranged. Example – 7+2=2+7 Example – 7+2=2+7 Example – 12+10=10+12 Example – 12+10=10+12

3
Commutative Property of Multiplication Definition – The product of a group of numbers is the same regardless of the order in which the numbers are arranged. Definition – The product of a group of numbers is the same regardless of the order in which the numbers are arranged. Example – 3 x 2 = 2 x 3 Example – 3 x 2 = 2 x 3 Example – 24 x 11 = 11 x 24 Example – 24 x 11 = 11 x 24

4
Associative Property of Addition Definition – The sum of a set of numbers is the same no matter how the numbers are grouped. 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
