Lehrer Lämpel vs Long Subtraction

Lehrer Lämpel is an educational app that supports primary school children (usually 3rd grade) to practise their multi-column addition skills. The standard addition method, where columns are processed from right to left, is supported. Steps are performed by easy drag & drop of numbers to the blackboard. The app offers an immediate feedback option where incorrect steps are immediately marked red and where correct steps are immediately marked green. Pupils can ask Lehrer Lämpel for help at any time. Help first removes an erroneously learner step; if there are no errors, a single step is performed towards the solution. All teacher steps towards the solution are followed-up with a step explanation as well. Various degrees of difficulty guided by the number of digits the two numbers can have, and whether carrying operations are required. Supports self-defined addition tasks, and there is a work-sheet, and there are randomised exercises. Supports English, French and German. Available on the iPad, for iOS9 or later. The app is ad-free. No data is being collected. Please consider leaving a review. This helps a lot. Thanks!

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.
