| Although he does experiments, and understands them, he does not do them much, or value them more than congruences. |
| More momentously, geometric proofs are guided by our deep ability to see points, lines, shapes and their symmetries, similarities and congruences. |
| And there are many other stunning congruences of sight and sound. |
| The operation coded in this command solves a system of two congruences using the Chinese Remainder Theorem. |
| In the second part, we opt for another approach of these congruences which are represented by partial orders. |
| We consider quotients of the free monoids by congruences which preserve the commutative image of words. |
