## Addition Concentrated Description
Solve addition problems of one-digit to five-digit numerals, either in the traditional right-to-left, column-by-column method; or in multiple choice mode, to select the answer from four choices.

Eight background color choices including white-on-black and black-on-white, for users with mild visual impairment.

Perfect for use with a classroom iPad.  Numerals, as displayed on the iPad, are large enough to be seen at a distance, so it's great for a group demonstration or a challenge between teams.
