Mathematical exercise with flexible configuration and detailed statistics.The counting limits are 0-10, 0-20 and 0-50 (1.0 beta). Available math operations are addition, subtraction, multiplication and division. Available modes are the comparison, the result determination, the determination of an unknown term and the operation determination. Configuring of the number of terms in the expression is available from two (A> B) to five (A + B * C = D + E). Detailed statistics include the count limit, the number of terms in the expression, the mathematical operations and mode. This program is suitable for training and testing of primary school students.
