What Are Mathematics Symbols?
Mathematics symbols are special signs or characters used to represent:
* Mathematical operations
* Numbers and values
* Relationships between numbers
* Shapes and measurements
* Sets, logic, and calculus concepts
Instead of writing long explanations, symbols help us express ideas quickly, clearly, and universally.
Example:
2 + 3 = 5
This short expression means two added to three gives five.
