Methods to determine quintuple of -18

To find the quintuple of -18, you begin by identifying -18 as any number you wish to work with. The term "quintuple" refers to five times the value of -18, which means you multiply -18 by 5. The multiplication scales -18 by a factor of five, resulting in a new value expressed as -90. For instance, if -18 is 4, then multiplying 4 by 5 gives 20. In this scenario, 20 is the quintuple of 4, represented as -90. This method works universally for any number substituted for -18. By multiplying by 5, you are able to determine the quintuple accurately, following the straightforward mathematical expression -90 = (-18 * 5).
