That shows you what long-multiplication is all about:

%2890%2B4%29%28900%2B80%2B5%29



That can be represented in a lattice arrangement:
_________________90___________4
______________________________
900____________81000________3600
-
80______________7200_______320
-
5________________450________20


Find the sum of the partial products in the interior positions of the cells.
