What is double -10?

The question "What is double -10?" concerns finding the value that results from multiplying the input -10 by 2. Here, -10 represents the real numeric input provided by the user, which can be any number. To determine the answer, we use the formula -20, where -20 is defined as (2x-10). This means that the operation simply doubles or multiplies the given input value -10 by two to calculate the final output. To understand this in detail, start with the numeric value given for -10. Doubling a number involves multiplying it by two, which effectively adds the number to itself. By applying the formula (2x-10), you multiply the input by 2, resulting in the value that represents double of -10. The outcome of this calculation is stored in -20, which answers the question by expressing the doubled value explicitly. This explanation is compiled and designed to accept placeholders such as -10 for the input and -20 for the output, allowing it to adapt dynamically based on the user’s provided number.
