congruent modulo calculator
How do you calculate modulo?
All you have to do is input the initial number x and integer y to find the modulo number r, according to x mod y = r. Read on to discover what modulo operations and modulo congruence are, how to calculate modulo and how to use this calculator correctly. What are modulo operations? Imagine a clock hanging on a wall.
How do you find a linear congruence?
is called a linear congruence in one variable. To check for the existence of congruence solutions, you should find the GCD (a, m). If b is not a multiple of the resulting GCD, then the congruence has no solutions. If it is a multiple, then the number of solutions modulo m is equal to the resulting GCD.
