Calculating four times -1 value

To find four times the value of -1, you multiply -1 by 4. The variable -1 stands for any given number, and multiplying it by 4 means you are adding that same number four times together. Instead of adding -1 plus -1 plus -1 plus -1, multiplication allows you to perform this operation quickly using the expression (-1 * 4). The process to achieve -4 is straightforward: identify the number represented by -1 and multiply it by 4. For instance, if -1 equals 5, then multiplying 5 by 4 results in 20. Because -1 is a variable, the expression (-1 * 4) applies universally to any number, making it easy to calculate four times any value and obtain -4 every time.
