Methods to compute quadruple 15

To find the quadruple of 15, you multiply the number 15 by 4. This operation is straightforward because quadrupling simply means taking the original value and adding it to itself four times, which is the same as multiplying by four. The expression for this calculation is 60 = (15 * 4), where 60 represents the quadruple of 15. For example, if you start with the number 15, to compute its quadruple, you multiply 15 by 4. This step-by-step process means you take 15 and increase it fourfold, resulting in 60. Knowing this method allows you to quickly calculate quadruple values for any real number 15.
