Questions and Answers

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
