What is double -2?

The question "What is double -2?" concerns finding the value that results from multiplying the input -2 by 2. Here, -2 represents the real numeric input provided by the user, which can be any number. To determine the answer, we use the formula -4, where -4 is defined as (2x-2). This means that the operation simply doubles or multiplies the given input value -2 by two to calculate the final output. To understand this in detail, start with the numeric value given for -2. Doubling a number involves multiplying it by two, which effectively adds the number to itself. By applying the formula (2x-2), you multiply the input by 2, resulting in the value that represents double of -2. The outcome of this calculation is stored in -4, which answers the question by expressing the doubled value explicitly. This explanation is compiled and designed to accept placeholders such as -2 for the input and -4 for the output, allowing it to adapt dynamically based on the user’s provided number.
