# Math Symbol C With Line Under: Set-Theoretic Concept!

The math symbol “C with a line under it” typically represents the **set-theoretic concept **of “subset” and is denoted as “⊆”. This symbol indicates that every element of one set is also an element of another set.

In set theory, a branch of mathematical logic, the symbol “⊆” is used to signify that one set is a subset of another set.

This means that if set A is a subset of set B, denoted as A ⊆ B, all elements of A are also contained within B.

This relationship does not necessarily imply that the sets are equal; however, if they are, A is both a subset of B and equal to B, which can be denoted by A = B or A ⊆ B and B ⊆ A.

**For example:**

- If A = {1, 2, 3} and B = {1, 2, 3, 4, 5}, then A ⊆ B.
- If A = {a, b} and B = {a, b, c}, again A ⊆ B.

The subset symbol “⊆” is fundamental in set theory, expressing the idea that all members of one set belong to another, a key concept in mathematical analysis and logic.
