Calculating quadruple -5

To calculate the quadruple of -5, you start by recognizing that quadrupling means multiplying by 4. The placeholder -5 represents any numeric value you choose. By multiplying -5 by 4, you effectively increase its value four times. For instance, if -5 represents 3, then multiplying 3 by 4 gives 12; this result, 12, is the quadruple of 3. Therefore, the formula (-5 * 4) generalizes this process for any input, allowing you to find -20 by performing this simple multiplication step.
