For this reason we have studied the fundamental notions of the elementary theory of numbers in the first place; then we started the resolution of the polynomial congruences. Throughout the work, the theory was always accompanied by practical examples of calculation. We have understand that concerning a polynomial congruence we can always decide if the congruence has a solution or not, where we can calculate the solutions if they exist.enPrime number, Modulus, Polynomial Congruence.Thesis
