Vynásobením

Vynásobením, commonly referred to as multiplication, is a fundamental arithmetic operation in mathematics. It is essentially a repeated addition of numbers. For example, 3 multiplied by 4 (written as 3 x 4) is the same as adding 3 to itself 4 times (3 + 3 + 3 + 3), which equals 12. The numbers being multiplied are called factors, and the result is called the product.

The symbol for multiplication is typically an 'x' or an asterisk '*'. In algebra, multiplication is often implied between variables or between a number and a variable, such as 2x, which means 2 multiplied by x.

Multiplication has several key properties. It is commutative, meaning the order of the factors does not change the product (a x b = b x a). It is also associative, meaning when multiplying three or more numbers, the grouping of the numbers does not affect the result ((a x b) x c = a x (b x c)). The distributive property links multiplication and addition: a x (b + c) = (a x b) + (a x c).

Multiplication is a crucial concept used in various fields, including science, engineering, finance, and everyday life, for tasks ranging from calculating areas to determining compound interest. It is one of the four basic operations of arithmetic, alongside addition, subtraction, and division.
