összeadás

Összeadás, also known as addition in English, is a fundamental mathematical operation that combines two or more numbers into a total sum. It is one of the basic arithmetic processes used to quantify, compare, and analyze quantities in various fields such as mathematics, science, engineering, and daily life.

The process of összeadás involves increasing a quantity by a specified amount or combining quantities to produce a new total. The numbers involved are called addends, and the result is known as the sum. For example, in the equation 3 + 4 = 7, the numbers 3 and 4 are addends, and 7 is the sum.

Összeadás is characterized by several properties, including commutativity (changing the order of addends does not affect the sum), associativity (grouping of addends does not affect the sum), and the existence of an identity element, zero, which when added to any number, leaves it unchanged.

The operation can be performed using various methods, from mental calculation to formal algorithms taught in arithmetic. It underpins more advanced mathematical concepts, such as algebra and calculus, and forms the basis for understanding number systems, measurement, and quantitative reasoning.

In practical applications, összeadás is used for budgeting, inventory management, data analysis, and numerous other tasks requiring the combination of quantities. Its simplicity and universality make it an essential component of education and everyday problem-solving worldwide.
