Description: Learn how to apply the distributive property of multiplication over subtraction and why it works. This is sometimes just called the distributive property or distributive law. Created by Sal Khan and Monterey Institute for Technology and Education. Rewrite the expression five times 9 minus 4 using the distributive law of multiplication over subtraction. Now, if we want to use the distributive property, well, you don't have to. You could just evaluate 9 minus 4 and then multiply that times 5.
