MathHelper Lite

MathHelper allows you to solve math exercises and get full steps of sollutionATTENTION: Finally! MathHelper opearates on English language (including built-in math reference)!!!

MathHelper is a unique application for students. The uniqueness of the application is that it allows us to see not only the answer, but a detailed solution of the problem. Now you do not need to order the work in math or ask for help from classmates - assistant in mathematics will do everything himself. In addition to solving problems, the application includes the theory on these topics and a scientific calculator.
MathHelper Lite allows you to solve a wide range of tasks.
