CalInverse is calculator with modular arithmetic and theory of numbers.
*Greatest common divisor (GCD) (Euclidean algorithm);
*Least common multiple (LCM);
*Modular multiplicative inverse;
*Chinese theorem for a system of 2, 3, 4 equations.
The program shows the methodology solutions.
The program contains a restriction of input value:
*The values are from 0 to 1290 for a system of 3 equations;
*The values are from 0 to 215 for a system of 4 equations;
*The values are from 0 to 46340 for other calculations.
The program does not require access to the internet.
