Addition is a fundamental arithmetic operation that combines two or more numbers to form a single result called the sum. It is one of the four basic operations in mathematics, alongside subtraction, multiplication, and division. Addition is used in everyday situations like counting objects, managing money, measuring quantities, and comparing totals. In symbolic form, it is represented by the plus sign (+), as in 3 + 2 = 5. The numbers being added are called addends. Addition also extends to more advanced areas, such as algebra, vectors, and matrices, where similar combination rules apply.
