What Is a Pair?
A pair is a set of two items that are usually related in some way. Pairs can be found in many different contexts, from mathematics to everyday life. In mathematics, pairs are often used to describe relationships between numbers or objects. For example, the number 2 and 4 form a pair because they have a relationship with each other (2 + 4 = 6).
In everyday life, pairs can refer to any two things that go together such as shoes and socks or peanut butter and jelly sandwiches. Pairs can also refer to people who share something special like siblings or best friends. The concept of pairing is important for understanding how things work together and why certain combinations make sense while others do not.
