Kids Subtraction Challenges is a creation of Inidimman Consultants who create educational applications for children of school age. The challenges are designed to reinforce mathematical learning by improving the speed and accuracy of children's mathematical calculations. These calculations are the building blocks for a wide variety of mathematical disciplines and for solving mathematical problems.

This application concentrates on subtraction, but includes some addition due to the simple, inverse relationship between the equations. As children become more and more able to recall their subtraction facts better and quicker, they become more efficient at problem solving. This classroom edition allows up to 30 students. The app has a log in screen and then tracks the progress of each individual.
