## Key Concepts

**Commutative Properties****Commutative Property of Addition:**- If \(a,b\) are real numbers, then \(a+b=b+a\)

**Commutative Property of Multiplication:**- If \(a,b\) are real numbers, then \(a\cdot b=b\cdot a\)

**Associative Properties****Associative Property of Addition:**- If \(a,b,c\) are real numbers then \(\left(a+b\right)+c=a+\left(b+c\right)\)

**Associative Property of Multiplication:**- If \(a,b,c\) are real numbers then \(\left(a\cdot b\right)\cdot c=a\cdot \left(b\cdot c\right)\)
