The purpose of the application is to encourage students in solvingmathematical expressions. The application allows students a fun wayto solve mathematical expressions. It is intended for students thatare 7 years old and older. Tasks are divided into 20 levels by thetype of mathematical operations. Students can play alone but theapplication allows also playing/solving mathematical expressions inthe group (thru WiFi connection). So can more studentssimultaneously solves the same cases and thus compete with eachother, which makes the application more interesting and fun.
