Explain how you know whether to add or subtract when you use the Distributive Property to multiply.

Well that depends on the operation within the parentheses. For example, in this one it's adding: 5 (4+3) so that would equal 5 (4) + 5 (3), and in this case: 4 (3-2) it's subtraction so it would equal to 4 (3) - 4 (2)
