## Subtraction Concentrated Description
Practice solving subtraction problems of one-digit to five-digit numerals.  Work column-by-column or by doing the math in your head and selecting from multiple choices.

Proper borrowing is enforced in the column-by-column mode.  You can display the borrowing in multiple-choice mode as a "helpful hint."

Five background color choices, including white-on-black (with no grayscale) for users with mild visual impairment.

Ideal for the classroom iPad, where the large numerals allow for demonstrations to a group or for team-based practices.

There are no ads, no in-app purchase, no interruptions, distracting sounds or music.  This was designed for an instructional setting.

### ***** "Helpful App"
Great app for practicing subtraction skills.  You can set the preferences for number of digits so you can control the level of difficulty.  Another nice feature is changing the background color of the app.
