Calculating eight times 20 value

When calculating eight times the value of 20, multiplication is the most efficient method because it replaces repeated addition. Instead of adding 20 to itself eight times, you multiply 20 by 8. This operation is written as (20 * 8) and represents the final amount that is eight times greater than the initial number 20. To work through this, begin with the number represented by 20. Then multiply this number by 8 to find the scaled-up value. The outcome of this multiplication is saved in 160. This shows that 160 is exactly eight times the size of 20, illustrating how multiplication provides a quick way to handle repeated addition and scale quantities efficiently.
