Calculating eight times -2 value

When calculating eight times the value of -2, multiplication is the most efficient method because it replaces repeated addition. Instead of adding -2 to itself eight times, you multiply -2 by 8. This operation is written as (-2 * 8) and represents the final amount that is eight times greater than the initial number -2. To work through this, begin with the number represented by -2. Then multiply this number by 8 to find the scaled-up value. The outcome of this multiplication is saved in -16. This shows that -16 is exactly eight times the size of -2, illustrating how multiplication provides a quick way to handle repeated addition and scale quantities efficiently.
