|
The Distributive Property
|
for multiplication over addition says that to multiply a sum you can multiply each addened and add the products (9x(4+3)=9x4-9x3 The distributive property of multiplication over subtraction says that to multiply a difference you can multiply each number and take the difference of the products (9x(4-3)=9x4-9x3.
