要计算几个集合并集的大小，我们要先将所有单个集合的大小计算出来，然后减去所有两个集合相交的部分，再加回所有三个集合相交的部分，再减去所有四个集合相交的部分，依此类推，一 …

Define the relation ∼ on Z × Z by (a, b) ∼ (c, d) if a − c = b − d. Show that ∼ is an equivalence relation. What is the equivalence class of (1, 2)? I'm not sure how to approach this since I've …

In mathematics, a tuple is an ordered sequence of values. The values can be repeated, but their number is always finite. A tuple is often represented by a comma-delimited list whose values …

C# 4-Tuples Tuples can be very handy for developers, allowing them to return multiple values from a function, the creation of composite keys to Dictionaries and eliminates structs or …

How do we find the number of ordered 4-tuples (a, b, c, d) such that a, b, c, d ∈ {1, 2, ⋯, 6} and a ≤ b ≤ c ≤ d? I tried to make cases, considering first different values of a, but they were just too …
