Write an expression that shows how you can multiply 9*475 using expanded form and the distributive property

475 = 400 + 70 + 5

therefore

9 * 475 = 9 * (400 + 70 + 5) = 9 * 400 + 9 * 70 + 9 * 5

=3600 + 630 + 45 = 4275

I think ... It's better to use Distributive Property:

(a - b) * c = a * c - b * c

9 = 10 - 1

therefore:

(10 - 1) * 475 = 10 * 475 - 1 * 475 = 4750 - 475 = 4275
