Etymology
The word comes from the Semitic root ع-د-ل (ʿ-d-l), which carries the sense of justice, fairness, and evenness. The Form III verb عادَلَ means to equalize or counterbalance something, treating two things as matching in weight or value. مُعادَلَة is the verbal noun of that verb, so it literally names the act of making two things equal, which is exactly what a mathematical equation states about its two sides.
