Calculating eight times -10 value

When calculating eight times the value of -10, multiplication is the most efficient method because it replaces repeated addition. Instead of adding -10 to itself eight times, you multiply -10 by 8. This operation is written as (-10 * 8) and represents the final amount that is eight times greater than the initial number -10. To work through this, begin with the number represented by -10. Then multiply this number by 8 to find the scaled-up value. The outcome of this multiplication is saved in -80. This shows that -80 is exactly eight times the size of -10, illustrating how multiplication provides a quick way to handle repeated addition and scale quantities efficiently.
