összeadására

Összeadására is a Hungarian word that translates to "adding" or "addition" in English. It refers to the fundamental mathematical operation of combining two or more numbers or quantities to find their total sum. This process is one of the four basic arithmetic operations, alongside subtraction, multiplication, and division.

In mathematics, addition is represented by the plus sign (+). For instance, 2 + 3 = 5 means that when 2 is added to 3, the result, or sum, is 5. The numbers being added are called addends, and the result is called the sum. Addition can be performed on integers, rational numbers, real numbers, and even complex numbers.

The concept of addition is intuitive and is often one of the first mathematical skills taught. It is used extensively in everyday life, from counting objects to managing finances. For example, if you have 3 apples and someone gives you 2 more, you would use addition to find the total number of apples you now have (3 + 2 = 5).

Beyond basic arithmetic, addition plays a crucial role in various branches of mathematics, including algebra, calculus, and set theory. In algebra, it is used to combine like terms in expressions. In set theory, it can be analogous to the union of disjoint sets. The properties of addition, such as commutativity (a + b = b + a) and associativity (a + (b + c) = (a + b) + c), are foundational to mathematical reasoning.
