Understanding methods to compute quadruple -5

To compute the quadruple of -5, we begin by understanding that -5 stands for any numeric value we choose. Quadrupling this value means taking -5 and multiplying it by 4. This operation increases the original number to four times its size, reflecting the concept of scaling a value by a fixed factor. The expression -20 = (-5 * 4) clearly shows how to perform this computation. By substituting -5 with an actual number, the multiplication process yields the quadruple. This step-by-step approach demonstrates that no matter the value of -5, multiplying it by 4 will always produce the correct quadruple, reinforcing the method's simplicity and reliability.
