👉 In mathematics, a "suborder" is a subset of an object that contains all its own elements and none of its own. In other words, it's a set of things that are contained within another set. For example, if you have a set A consisting of 10 integers {2, 3, 4, 5, 6, 7, 8, 9, 10}, and you define the suborder B as containing all elements in A
