Calculating four times 20 value

To find four times the value of 20, you multiply 20 by 4. The variable 20 stands for any given number, and multiplying it by 4 means you are adding that same number four times together. Instead of adding 20 plus 20 plus 20 plus 20, multiplication allows you to perform this operation quickly using the expression (20 * 4). The process to achieve 80 is straightforward: identify the number represented by 20 and multiply it by 4. For instance, if 20 equals 5, then multiplying 5 by 4 results in 20. Because 20 is a variable, the expression (20 * 4) applies universally to any number, making it easy to calculate four times any value and obtain 80 every time.
