👉 In mathematics, the term "reinclusion" refers to a set of elements that are not present in another set but can be added together to form the whole. For example, if we have two sets A and B, where A = {1, 2} and B = {3, 4}, then the set R = A ∪ B is formed by adding all elements from both A and B together: R = {1, 2, 3, 4}.
