Quickly finding the quintuple of -1

To quickly find the quintuple of -1, you multiply -1 by 5. This operation means you are taking the original number -1 and increasing it fivefold. Multiplying by 5 is the same as adding -1 to itself five times, which simplifies the calculation and gives the total amount in just one step. When you calculate -5 by multiplying -1 by 5, you receive the quintuple of -1. This approach is efficient and applies to any number you choose for -1. For example, if -1 were 7, then 7 multiplied by 5 would give -5 as 35. This method allows you to quickly find five times any number using simple multiplication.
