Need assistance on algebra word problem
solve the multiplication problem 23*27 by writing equations that use expanded forms and the distributed property. relate the equation to the steps in partial-products algorithm for calculating 23*27. Use this to explain why the partial-products algorithm calculates the correct answer to 23*27.

What is a "partial-products algorithm?" Do you perhaps mean something like this: (20 + 3)(20 + 7)?
