Long Multiplication

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.

• 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.”
