Question 1

commutative property

Answer 1

• order doesn’t matter
• numbers can “commute”, or move
• addition/multiplication

Question 2

associative property

Answer 2

• consider an expression with 2+ operators of the same kind
• associativity implies that the order in which the operations are performed does not change the outcome
• or, if you used parantheses, the placement wouldn’t matter
• (a + b) + c == a + (b + c)
