Subset Of Or Equal To Symbol
⊆ indicates that one set is a subset of another, allowing equality.
U+2286
The symbol ⊆ means “subset of or equal to.” It’s commonly used in math, logic, and set notation to compare two collections. You can copy it directly or use standard code escapes.
Subset Of Or Equal To Symbol Meaning
⊆ (Unicode name: SUBSET OF OR EQUAL TO, U+2286) expresses that all elements of one set are also contained in another set, with the possibility that the two sets are exactly the same. In set terms, A ⊆ B means “every member of A is in B,” and additionally A may equal B. This is distinct from ⊂, which typically indicates a proper subset (A is contained in B but not equal). You’ll see ⊆ in proofs, definitions, and constraints when describing containment relationships between groups of items.
Common uses
- •Set comparisons in math notes and homework
- •Writing conditions in logic statements (e.g., allowed elements are contained)
- •Describing constraints in data schemas (one field’s allowed values within another’s)
- •Reasoning about collections in programming discussions using set notation
- •Labeling relationships in diagrams and educational charts

FAQ
What does ⊆ mean?
⊆ means “subset of or equal to.” It states that every element of the first set is also in the second set, allowing the two sets to be equal.
How is ⊆ different from ⊂?
⊂ typically indicates a proper subset (contained but not equal), while ⊆ allows equality (contained and possibly identical).
How can I copy ⊆ from this page?
Use the symbol at the top of the page (⊆) and paste it directly into your document, message, or code editor.
What is the Unicode information for ⊆?
Unicode code point is U+2286, with HTML entity ⊆ and escapes such as CSS \\2286 and JavaScript \\u{2286}.
