Calculating eight times 12.5 value

When calculating eight times the value of 12.5, multiplication is the most efficient method because it replaces repeated addition. Instead of adding 12.5 to itself eight times, you multiply 12.5 by 8. This operation is written as (12.5 * 8) and represents the final amount that is eight times greater than the initial number 12.5. To work through this, begin with the number represented by 12.5. Then multiply this number by 8 to find the scaled-up value. The outcome of this multiplication is saved in 100. This shows that 100 is exactly eight times the size of 12.5, illustrating how multiplication provides a quick way to handle repeated addition and scale quantities efficiently.
