Solving math examples

An irreplaceable assistant in the study and teaching of mathematics, containing the following sections: 1.1 Solution of arithmetic examples (addition, subtraction, multiplication and division) of any length of numbers, number of elements and combinations of brackets. The decision is made on the basis of strict adherence to the mathematical rules of the sequence of actions, with the display of each step of the solution and the corresponding explanation. 1.2 Comparison of numbers and expressions of any length of numbers, number of elements and combinations of brackets. Determination of the greater, lesser part or equality from the specified data. 1.3 Column calculator, enter the appropriate values: - division by a column (dividend and divisor); - multiplication by a column (1 multiplier and 2 multipliers); - addition by a column (1 term and 2 terms); - subtraction by a column (decreasing and subtracting), and the program will independently calculate with the display of all stages of the solution (the result at each step, the final answer, the remainder). Operations with numbers up to 15 digits (999 999 999 999 999) are possible. Maintaining and saving an archive of the last 100 calculations. 1.4 Greatest common divisor (GCD), least common multiple (LCM). 1.5 Games simulators for study and repetition. Different types of tests (solving examples for a while, until the first error, for the total number of errors) with saving the results in the progress table: - multiplication table; - any examples (basic operations, exponentiation, root extraction);
