The Partial Products Multiplication iPhone App
This app can be used to teach and study the partial products multiplication method. The app is easy to use and it has an intuitive interactive interface with customizable colors and other settings. The user can solve random multiplication problems.
The Partial Products Multiplication Method
The partial products multiplication method is a two-step process. In the example 39 x 24, each place value is first multiplied separately. The partial products are added and 36 + 120 + 180 + 600 produces the answer 936.
In the Everyday Mathematics curriculum the partial products method is the focus algorithm for multiplication.

The numbers are aligned automatically so that the user can concentrate on solving the operations for each column.
After you solve the operation for each partial product the correct answer will fly to the right place. If you press the wrong button the answer will appear above the keyboard but it will not move.
