Long Multiplication helps students learn and practice the standard long multiplication method step by step.
The app shows each part of the long multiplication process visually. Students multiply and add one step at a time, and animated numbers move into the correct places. This makes the column method easier to understand and practice.
Long Multiplication can be used for classroom teaching, individual practice, tutoring, or homework support. Problems can be generated by the app or entered manually.
Features:
- Step-by-step long multiplication practice
- Multiplicand can have up to 5 digits
- Multiplier can have up to 4 digits
- Supports decimal numbers
- Students can enter their own problems
- Current operation for each column can be hidden
- Operands for the current operation can be highlighted
- Five visual themes
- Native interfaces for iPhone and iPad
Reviews and Recognition:
Reviewed by Wired.com as part of “A Set of Excellent iPhone Math Apps for the Older Child.”
Teacher endorsement:
“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.”
— Rita Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada
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.”

I love this app and used to use it in my fourth grade classroom throughout my multiplication unit as a great opportunity for differentiated, engaging practice with instant feedback! I am very disappointed with the new update though, since it makes the app no longer compatible with my 2nd generation iPods. In the world of education, it is not easy to get the newest technology offered especially when as of 3 years ago my district bought me enough iPods for each of my students. I wish I could still use this app on my class set of iPods, but they can no longer be updated with new software versions. Please allow your apps to continue to work with the older iPod software versions since this was created to help teachers and students in the first place.
Wonderful for teaching multiplication!

This app does a great job at showing kids the steps in solving a multi-step multiplication problem. They get more practice with a concept that is difficult for many to learn (especially my special needs students) beyond the simple learning of multiplication facts. Great APP!!
Ok but not that exciting or creative.

This summer I wanted to get some multiplication Apps for 9 yr old son so he could keep up his skills for the 4th grade. An Educational App for a child should be entertaining while they are learning. The App should keep the attention of the child and make the child want to "play" with it. There are many ways to do this. None of which are in this App. There are no explanations, no music, no rewards, nothing. It's just plain and to honest rather boring. This App is good for a teaching aid when reviewing but even then it's boring. There are much better Apps out there not to mention cheaper too. 3.99 is way too much to pay for this App. I would of given the App 3 stars but at 3.99 it got bumped down to only 2 stars.
Updated for iOS 26 compatibility.
