Question

a. Commutative property of addition (lessons 3 & 6): the property of operations that says addends can be in any order and it will NOT change the sum; a + b = b + a
b .Distributive property of multiplication over addition (lessons 3 & 4): the property of operations that says multiplying the sum of two or more addends by a number is the same as multiplying the number by each of the addends individually and adding the products; a(b + c) = ab + ac and ab + ac = a(b + c)
c . Identity Property of Multiplication (lesson 6) – the property of operations that says that the product of any number and 1 is that same number; a ∙ 1 = a

Answer 1

a. Commutative property of addition (lessons 3 & 6)
c. Identity Property of Multiplication (lesson 6)
