Mathematical calculations description

The program performs calculations in the following chapters of mathrmatics
1. Matrix calculations
- the determinant of matrixes with integer coefficients solving
- the inversion of matrixes with integer coefficients calculating
- multiplication of matrixes calculation
- the rank of matrixes with integer coefficients solving
2. Calculating the roots of polynomials of degrees 2,3,4 with integer coefficients
3. Calculating a solution to systems of linear aquations with integer coefficients of degrees 2,3,4,5,6
4. Computing truth tables of logical epressions
5.The program allows to solve common linear programming problem and transportation problem.
To solve transportation problem one can use the following methods:
1. Northwest corner method
2. Minimum cell cost method
3. Vogel's approximation method
4. Stepping-stone method
