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.
