Explanation

To quickly find the quintuple of -81, you multiply -81 by 5. This operation means you are taking the original number -81 and increasing it fivefold. Multiplying by 5 is the same as adding -81 to itself five times, which simplifies the calculation and gives the total amount in just one step. When you calculate -405 by multiplying -81 by 5, you receive the quintuple of -81. This approach is efficient and applies to any number you choose for -81. For example, if -81 were 7, then 7 multiplied by 5 would give -405 as 35. This method allows you to quickly find five times any number using simple multiplication.
