Quickly finding the quintuple of -3

To quickly find the quintuple of -3, you multiply -3 by 5. This operation means you are taking the original number -3 and increasing it fivefold. Multiplying by 5 is the same as adding -3 to itself five times, which simplifies the calculation and gives the total amount in just one step. When you calculate -15 by multiplying -3 by 5, you receive the quintuple of -3. This approach is efficient and applies to any number you choose for -3. For example, if -3 were 7, then 7 multiplied by 5 would give -15 as 35. This method allows you to quickly find five times any number using simple multiplication.
