Calculation:

The congruence is$25\equiv 85\text{}mod\text{}12$ .

Consider$\frac{25-85}{12}$ ,

$\frac{25-85}{12}=-60/12=-5$

Because -5 is an integer,$25=-85\text{}mod\text{}12$ is a true congruence.

Hence, the congruence

25$\frac{25-85}{12}85\text{}mod\text{}12$ is true.

The congruence is

Consider

Because -5 is an integer,

Hence, the congruence

25
