5×2

5×2 is a basic arithmetic expression representing the product of the integers 5 and 2. The symbol × denotes multiplication, and the result is called the product. In base-10 notation, 5×2 equals 10. The expression can be understood in several ways: it represents two groups of five objects, and it also corresponds to the area of a rectangle with sides of length 5 and 2, which is 10 square units. As a simple case of the doubling concept, multiplying by 2 doubles the quantity of 5, yielding 10.

5×2 is commutative: 5×2 = 2×5. It also participates in standard arithmetic laws, such as the distributive property: a×(b+c) = a×b + a×c, which for example gives 5×(2+3) = 5×2 + 5×3 = 10 + 15 = 25.

Notation and usage: the × symbol is common in many contexts, but other forms exist, such as the middle dot · or juxtaposition, as in 5(2) or 5·2. In programming, multiplication is typically shown with an asterisk (*) rather than ×. The concept of 5×2 appears in elementary education as part of multiplication tables and basic arithmetic practice.

Applications and significance: as a foundational operation, 5×2 illustrates basic multiplication, supports quick mental math, area calculations, and the broader study of arithmetic and algebra.
