Endorsed by teachers
Rita Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada:
"The math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary.
They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice. Being able to adjust the level of difficulty to suit their needs is also very motivating for the students. I am so glad to have come across this great educational tool!"
Kelly Tenkely, iPad Curriculum:
"The step by step animation and guidance will help students get the column method of multiplication down in no time. The ability to enter their own numbers means that students can input problems from a math curriculum or textbook and work through the step-by-step process with any problem. Your reluctant math students will love this app, it will act as their own personal tutor sitting with them and encouraging them on!"
The long multiplication method
In arithmetic, long multiplication is the standard procedure suitable for multiplying numbers. The method breaks down a multiplication problem into a series of easier steps.
Easy to use
The Long Multiplication math app allows the user to solve a long multiplication problem step by step and animates all the steps. In the steps the user will multiply or add. The correct answer will fly to the right place. If the user presses the wrong button the answer will appear above the keyboard but it will not move.

Feedback and requests for new features
I keep updating all of my apps and all kinds of feedback and suggestions are welcome.
The lower number can now have up to 4 digits instead of 1 or 2. This means that you can now multiply a 5 digit number by a 4 digit number.
This update was requested by a teacher. Please visit idevbooks.com or send email to firstname.lastname@example.org if you have any feedback, requests for new features, or questions.
iDevBooks also has 20 other math apps on the App Store.
