Methods to find quadruple -1

When you want to find the quadruple of -1, you are essentially looking to calculate four times the value of -1. This means you multiply -1 by 4 to scale it up to four times what it was originally. Multiplying by 4 is the direct method to achieve this result. By applying the multiplication (-1 * 4), you obtain -4. This expression gives the quadruple of -1. This method works for any number and is a fundamental technique for increasing a value by a factor of four.
