大家好，最近在學習不等式的概念，但是網路上有inequation和inequality這二個字，請問這二個字的差別在哪裡？
根據wikipedia的定義來看，分別有以下的解釋，但是我看不懂.. = =
equality is the state of being quantitatively the same. More formally, equality (or the identity relation) is the binary relation on a set X defined by { (x, x) | x e X }
inequation is a statement that two objects or expressions are not the same, or do not represent the same value. This relation is written with a crossed-out equal sign as in x != y
