Order of Operations Review

Order of Operations Review

Let's review order of operations!

Important Properties of Operations

• Commutative Properties of Addition and Multiplication (A+B=B+A, A*B=B*A)

• Associative Property of Addition: A+(B+C)=(A+B)+C

• Associative Property of Multiplication: A*(B*C)=(A*B)*C

• Distributive Property: A(B+C)=AB+AC

• Inverse Property of Addition: A+-A=0

• Inverse Property of Multiplication: A* 1/A=1

• Identity Properties of Addition and Multiplication: A+0=A; A*1=A

Multiple Select

Which of the following statements represent the COMMUTATIVE properties?

• A(B+C)=AB+AC

• A+B=B+A

• A+(B+C)=(A+B)+C

• A*B=B*A
