2×7
2×7, read as two times seven, is the product of the integers 2 and 7. In decimal arithmetic it equals 14. It can be computed by adding 2 to itself seven times or by adding 7 to itself twice; both methods yield 14. The operation is commutative, so 2×7 = 7×2.
The product 14 factors as 2 × 7, making it an even composite number. In modular arithmetic,
In broader applications, 2×7 can describe dimensions in grids or matrices, such as a 2×7 array containing
