Can you use subtraction with the distributive property?

Wrong! See below. No, you cannot use the distributive property for subtraction. Let's say that your expression is: (5 + 4) - 3 We know that parentheses must be handled first, so we know that the correct answer is: (5 + 4) - 3 = 9 - 3 = 6. But let's say that you tried to use the distributive propertyand applied "- 3" to each term in the parentheses. You would get: (5 + 4) - 3 = (5 - 3) + (4 - 3) = 3 In fact, you would have subtracted not 3, but 6! * * * * * All very true except that this is the associative property - not distributive The distributive property, which IS valid, gives a*(b - c) = a*b - a*c
