15×20

15×20 is a simple arithmetic expression representing the product of the integers 15 and 20. The symbol × denotes multiplication. In base-10 arithmetic, the result is 300.

Computation: 15×20 can be computed directly as 15 times 20 equals 300. It can also be seen via the distributive property: (10+5)×20 = 200+100 = 300.

Geometric interpretation: If a rectangle has sides measuring 15 units and 20 units, its area is 15×20 = 300 square units. The units depend on the measurement system used.

Factorization and properties: The prime factorization of 15 is 3×5, and of 20 is 2^2×5; hence the product 15×20 equals 2^2×3×5^2 = 300. The product is even and divisible by 3 and 5, among other factors.

Use and occurrences: The product is common in measurements and design, where a 15-by-20 dimension may define a rectangle or component, yielding an area of 300 square units when units are consistent.
