Write an expression that shows how to multiply 7 x 256 using expanded form and Distributive property.

To multiply any number using expanded form and Distributive property, we need two steps:

1. Write the greater factor in expanded form, and

2. Record partial products by using Distributive property.

Step 1.

7 x 256 = 7 x (200 + 50 + 6)

Step 2.

7 x (200 + 50 + 6) = 7 x 200 + 7 x 50 + 7 x 6

Hence, the complete expression should look like:

7 x 256 = 7 x (200 + 50 + 6) = 7 x 200 + 7 x 50 + 7 x 6
