Counting-Up Subtraction

By Esa Helttula

Description

The counting-up subtraction app lets students solve subtraction problems by counting up from the lesser number step by step. The first step is to get to the nearest multiple of 10.

Features:

- The numbers can have up to 3 digits
- You can set your own problems
- The current operation for each column can be hidden
- The operands for the current operation can be highlighted
- Three different themes
- Native interfaces for iPhone, and iPad
