Long Multiplication vs Long Subtraction

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.” Other iDevBooks Math Apps: Other iDevBooks math apps include Column Addition, Column Subtraction, Long Division, Lattice Multiplication, Visual Multiplication Table, Fraction Math, Partial Differences Subtraction, Partial Quotients Division, Partial Sums Addition, Decimal Rounding, and more.

We created this Long Subtraction Calculator app because we believe learning and mastering the long subtraction method for solving subtraction problems is crucial in order to gain a solid understanding of subtraction. Use this app to learn how to solve subtraction problems using the long subtraction method. Simply enter different subtraction problems and see how different problems are solved. The answer to a subtraction problem is called a difference. Furthermore, the number you start with is called the minuend, and the number you subtract from the minuend is called the subtrahend. This app also includes tools to find the minuend and the subtrahend if you already know the difference and one of the other parts of a subtraction problem. The app is fast, intuitive, and easy to use. It is a standalone app, which means that it will work perfectly fine in places with little or no Internet access. We hope that the Long Subtraction app will become one of your favorite math apps.
