True or false: abc = cba

• True

• False, if c = 0.

• False, if a > b.

• False, three variables can't multiply.

Identify the property

What is the additive inverse of 2/3?

• -2/3

• 3/2

• 2/3

• -3/2

Pick the answer that is an example of the commutative property of multiplication

• b + c + a = a + b + c
• a(b + c) = ab + ac
• a ⋅ b = b⋅ a
• a ⋅ 1 = a
