What is the result of applying the commutative property of addition?

a + b = b + a (correct)

a - b = b - a

a + b = -b + a

a × b = b × a

Which property states that when adding or multiplying three or more numbers, the way in which the numbers are grouped does not affect the result?

Additive Property

Associative Property (correct)

Commutative Property

Distributive Property

What is the distributive property of multiplication over subtraction?

a × (b + c) = a × b + a × c

a × (b - c) = a × b - a × c (correct)

a × (b - c) = a × b + a × c

a × (b + c) = a × b - a × c
