Calculating quadruple 20

To calculate the quadruple of 20, you start by recognizing that quadrupling means multiplying by 4. The placeholder 20 represents any numeric value you choose. By multiplying 20 by 4, you effectively increase its value four times. For instance, if 20 represents 3, then multiplying 3 by 4 gives 12; this result, 12, is the quadruple of 3. Therefore, the formula (20 * 4) generalizes this process for any input, allowing you to find 80 by performing this simple multiplication step.
