Calculating eight times -20

The idea behind calculating eight times -20 is to multiply the number -20 by 8. Multiplication by 8 can be thought of as adding -20 together eight times. For example, if -20 is 3, then adding 3 eight times (3+3+3+3+3+3+3+3) gives the same outcome as multiplying 3 by 8, which is the product expressed as -160. To perform this calculation, you take the variable -20 and use the expression (-20 * 8). This means you scale the value of -20 by eight, directly increasing it to eightfold its original size. The result -160 is a straightforward representation of this multiplication and can be applied to any real number value of -20, showing a fundamental arithmetic operation clearly and effectively.
