Calculating four times -10 value

To find four times the value of -10, you multiply -10 by 4. The variable -10 stands for any given number, and multiplying it by 4 means you are adding that same number four times together. Instead of adding -10 plus -10 plus -10 plus -10, multiplication allows you to perform this operation quickly using the expression (-10 * 4). The process to achieve -40 is straightforward: identify the number represented by -10 and multiply it by 4. For instance, if -10 equals 5, then multiplying 5 by 4 results in 20. Because -10 is a variable, the expression (-10 * 4) applies universally to any number, making it easy to calculate four times any value and obtain -40 every time.
