1×25

1×25 is a mathematical expression representing the multiplication of 1 by 25. In arithmetic, the product of 1 and 25 is 25, as shown by the equation 1 × 25 = 25. This expression is fundamental in basic mathematics, illustrating the multiplicative identity property (where any number multiplied by 1 remains unchanged). It may also appear in contexts such as matrix dimensions (e.g., a 1×25 matrix has one row and twenty-five columns) or component specifications (e.g., a 1x25 resistor pack), though its primary association remains with arithmetic operations. The simplicity of the expression makes it a common example in educational materials to teach multiplication concepts.
