înmulirii

Înmulțirea is the Romanian word for multiplication, a fundamental arithmetic operation. It is one of the four basic operations in elementary mathematics, alongside addition, subtraction, and division. Multiplication can be thought of as repeated addition. For example, 3 multiplied by 4 (written as 3 × 4 or 3 ⋅ 4) is the same as adding 4 to itself three times (4 + 4 + 4), which equals 12. Similarly, it can be seen as adding 3 to itself four times (3 + 3 + 3 + 3), also equaling 12.

The numbers involved in a multiplication problem are called factors. The result of a multiplication is called the product. The commutative property of multiplication states that the order of the factors does not change the product (a × b = b × a). The associative property states that when multiplying three or more numbers, the grouping of the factors does not affect the product ((a × b) × c = a × (b × c)). The distributive property relates multiplication to addition and subtraction: a × (b + c) = (a × b) + (a × c).

Multiplication is used extensively in various fields, including algebra, geometry, calculus, and science. It is essential for calculating areas, volumes, rates, and many other mathematical and real-world quantities. The concept of multiplication extends beyond integers to rational numbers, real numbers, and even complex numbers, forming the basis for more advanced mathematical concepts.
